• Can herd with any herbivore even when they are nesting.

• Skittish in nature.

Psittacosaurus

• Herd Size| Unlimited.

• Nesting| N/A

• Avoids| Every carnivore.

Psittacosaurus, more commonly called the “Taco”, is the smallest herbivore present on Isla Nycta, and supports much of the carnivorous ecosystem. Small and skittish in nature, these harmless creatures roam the island looking for berries and small plants to eat.

While not as sophisticated as modern animal societies, these creatures will often group together for safety, and behave similarly to modern prairie-dogs, chattering away until one of their number, a designated sentry, sees a threat (usually anything carnivorous) which leads to cries of alarm, and the group scattering for cover.

In these cases, anything will do.

Dead bodies, larger herbivores, rocky holes, bushes, tall grass, anything that can provide them with a safe place to hide is free game for a scared Taco. Field studies conclude it is hardly a threat to humans, and is at worst a lousy tasting survival food.

• Can herd with any herbivore.

• Often loud and overly bold, known to nip at larger creatures and run away.

• Commonly a scout for herbivore herds.

Dryosaurus

• Herd Size| Unlimited.

• Nesting| Unlimited.

• Avoids| Wary of anything bigger than itself but known to be ankle biters when feeling 'brave'.

The Dryosaurus is one of the more obnoxious creatures present on Isla Nycta. Often called the “Dryo”, some researchers have noted strange, overly bold behavior from these small green herbivores, and have even come to call them “The True Apex” of the island. Dryosaurs are noisy, so much so that they are often chased away by both herbivores and carnivores for being too loud. The loudest often form massive colonies together. The quieter of them, however, can sometimes find a place among a herd of larger creatures as a scout of sorts. Dryos are often seen skittering between the legs of bigger herbivores for protection, or ahead of a herd as a sort of trailblazer, letting out panicked chirps if they find something with teeth. Their surprising speed and agility allows them to avoid most of the larger creatures on the island.

As far as their supposed bravery, it has been noted that Dryosaurs often seem to threaten things far larger than themselves, sometimes even attempting to nip at their heels before fleeing to the safety of their burrows, leaving the would-be hunter dumbfounded. This doesn’t seem to cause any lasting harm to the predator, but is curious behavior to say the least. Some have come to suggest that this is actually some sort of game, or perhaps a way to earn respect among their larger peers. Or maybe they are simply unaware of their actual size. More interestingly, this behavior is even more prominent with larger groups of Dryosaurs. Regardless, the Dryo seems to present no major harm to humans, other than being horribly noisy and a bother...

  • Solo| Tier 4+ Carnivore Packs (3+), Acros, Apexes.

  • Paired| Acro Pairs, Acro Pack, Tier 4+ Carnivore Packs (3+), Apexes.

  • Herd (3+)| Acro Pack, Apex Pair.

The Diabloceratops is well-named despite their small stature when compared to their bigger cousins. Simply called “Diablos” or “Dibbles” these creatures are territorial and vocal about it. Large herds aren’t afraid to charge almost anything that isn’t a set of paired apex predators if they are threatened or attacked.

Unlike the Triceratops, the Diablo is very fast and nimble, and though their smaller stature means they can’t take as many blows, their horns and rowdy temperament often cause them to get behind a predator and gore them repeatedly. However, in spite of this, they’re a favorite food for Allosaurus packs and Ceratosaurs, as well as the occasional apex predator. While threats to the Dibble aren’t always plentiful, they often find additional safety and companionship by herding with their larger cousins, the Triceratops, and share the same general aggression toward hadrosaurs of all kinds as well.

When babies are around, just about anything that isn’t a ceratopsian or smaller than a Diablo will want to stay away, as they are known to threaten, charge, or attack until the predator, or other herbivore, leaves. This behavior often leads to groups of Dryosaurs or other smaller herbivores taking shelter among Dibble herds, hiding safely behind the lines of their protective “Dibble Knights” as the small ceratopsians protect themselves and their young from harm. As a result of this aggressive behavior, Diablos are considered quite dangerous while nesting, but can actually be unexpected allies for humans on the run from predators, as they seem to see humans in a similar way to Dryosaurs and other smaller creatures.

The second of Isla Nycta’s common hadrosaurs is the “Maia” or Maiasaurus. These animals are incredibly social, and are seen in large herds. True to their namesake of “Good mother lizard”, Maias go to incredible lengths to defend their young, and herd, from harm. If one of the herd is wounded, the rest will stand around it to protect them until they are healed enough to move, threatening anything that gets too close, and even attacking other large creatures to keep them away.

If forced to flee due to encountering large apex predators, the entire herd tries to move as one, with young ones in the center setting the pace, and all members on alert for attacks. Because of this behavior, smaller herbivores like Gallimimus or Dryosaurus like to use Maia herds as protection. Paras also enjoy herding with Maias for this reason, and it isn’t uncommon to see large mixed herds traveling from place to place in search of water and food. They also share the inbuilt hatred of ceratopsians common among all hadrosaurs, and will seek to challenge them away from food or water, with the entire herd lining up and threatening for a frightening display. During mating season, Maias are communal, with the entire herd raising children and caring for them until they reach young adulthood. They are, by nature, protective creatures, and are distrustful of humans if one of their number are injured, or they have young. Otherwise, they seem not to mind interacting with humans so long as they do not prove themselves a threat.

• Can herd with any herbivore.

• Quiet and passive in nature.

  • Paired| Cerato, Tier 4+ Carnivore.

  • Herd (3+)| Tier 4+ Carnivore Pair/Pack, Apexes.

One of the more shy creatures on Isla Nycta has to be the Pachycephalosaurus or “Pachy”. While uncertain, this seems to stem from the fact that these dinosaurs are often fairly meek, paranoid little creatures and prefer to stay out of sight to care for children, generally keeping to themselves. The only time they will group up into larger herds is when it comes time to nest. Due to their passive nature, Pachys get along well with many, if not all, of the island’s herbivores though are still quite the challenge to smaller carnivores should they become a threat. In fact, the most common way to see a large group of Pachies is tagging along with a group of bigger, stronger herbivores for additional protection. While they eat plants, they do happen to be somewhat hostile to humans, often threatening them or making mock charges until the intruder leaves, especially with young around. Getting hit by a charging Pachy feels like taking a rampaging football-player to the chest, and has been known to easily break ribs or cause concussions.

• Aggressive toward Ceratopsians.

• Stego, Anky and Theri can follow from a distance.

• Often loud unless traveling at night.

Parasaurolophus

  • Paired| Acro Pairs, Acro Pack, Apexes, Tier 4+ Carnivore Packs (3+).

  • Herd (3+)| Apex Pair, Acro Pack.

The Parasaurolophus or “Para” is one of the most easily recognizable animals present on Isla Nycta, and not just because of their trademark curved crests. The bellowing cries of these plant-eaters can carry for miles across the island, rivaled only by the loud cries of Triceratops herds. The most common of a handful of hadrosaurs that populate the island, these creatures have a large appetite, and spend time wandering between food sources. They also have a vicious rivalry with ceratopsians and they do not at all enjoy sharing food or water with each other. Paras are otherwise welcoming to other hadrosaurs, and mixed groups of Maiasaurs, Paras, and the larger Shantungosaurus are not uncommon. Mating season sees male Paras “boxing” for the right to mate with a female, forelimbs flailing at one another and calls being made until one backs down, bloodied and beaten. These clashes are very rarely deadly though. As with most herbivores, Parasaurs seem not to care about humans unless there are juveniles around, in which case they will be threatened and chased away from the nest.

• Can herd and nest with any herbivore.

• Quiet and prefers quiet.

• Actively avoids Stegos and will leave a herd if there's more Stegos than Ankys.

Ankylosaurus

• Herd Size| 8 adults + unlimited juvis.

• Nesting| Unlimited, must leave at .8 (fresh adult) stage if the herd is full.

• Avoids| Actively avoids Stegos.

  • Solo| Acro Pairs, Acro Pack, Apexes.

  • Paired| Acro Pack, Apex Pair.

  • Herd (3+)| Nothing.

The Ankylosaurus is as close to a tank as about any living thing can get. The “Anky”, as it is called in shorthand, is a herbivore with a severe case of introversion. They enjoy quiet spaces to graze, away from noisy creatures, and aren’t shy about swinging their clubbed tails as if to tell their neighbors to shut up. They aren’t complete loners, though, and will typically follow herds of other herbivores, but from a distance.

Their heavy bone armor grants them protection from many predators, but if something threatens the herd, young will gather near the adults’ heads while the adults face their tails toward the attackers, all the while honking and hooting and slamming their clubs into the ground as a warning. The only herbivore that the Anky seems not to like in general is the Stegosaurus, likely due to their loud and brutish behavior. If the Anky is the bookworm, the Stegos are the jocks, and as a result, Ankylosaurs will actively seek to avoid being near Stegosaurs, often leaving a mixed herd if there are more Stegos than Ankys.

With the exception of when they have young, Ankys seem not to care much about humans, as long as they keep quiet and don’t interfere with them or show themselves to be a threat.

• Herds with Ceratopsians and smaller non-Hadrosaur herbivores.

  • Solo| Apex Pair.

  • Paired/Herd (3+)| Nothing.

The Triceratops or “Trike” is one of the only herbivores on Isla Nycta that I’ve seen fight a Tyrannosaurus and win. They are large, powerful, social herbivores that often dominate over mixed herds of other ceratopsians like Diabloceratops and Avaceratops, and are a force to be respected by virtually every creature on the island. While not as aggressive as the Stegosaurus, a Trike family is still dangerous, and will threaten, headbutt, stomp, or mock-charge anything that gets too close that could be a threat.

During mating season, males will often fight for control over a group of females until one backs down and ends the challenge, after which females will lay one egg each, sired by the winning male. Sometimes there is a beta male in a herd, often a familiar companion to the alpha male, or sometimes a sibling. These males will look after the herd and provide their genes for the next generation, although groups of all male or all female Trikes isn’t unheard of either.

Unlike many herbivores, Trikes prefer to linger in an area, often claiming territory to graze and raise young. This usually includes water and a food source, and the Trikes will bully off threats to themselves or their food, especially hadrosaurs. Hadrosaurs and Ceratopsians actively compete for food and water sources, actually treating one another as enemies or threats similar to how they might treat a carnivore.

While they act aggressive to any hadrosaurs like Maiasaurs and Parasaurs, they tolerate most other herbivores as long as they keep their distance. The exceptions are other ceratopsians and small herbivores, which they will usually allow to mingle with the herd. While aggressive to many things, Trikes are known to be loving parents, protecting their young until they come of age and either join the herd, or, if male, are sent away to find their own herd of females. While dangerous to humans if nesting, Trikes will typically not bother or pay much attention them as long as they don’t show themselves to pose a threat.

• Herds with Hadrosaurs and smaller non-Ceratopsian herbivores.

• Aggressive toward Ceratopsians.

Shantungosaurus

• Nesting| Unlimited. Must leave at .6 (fresh adult) stage if the herd is full.

• Avoids| Always avoids Ceratopsians.

  • Solo| Apex Pair.

  • Paired/Herd (3+)| Nothing.

The largest hadrosaur on the island is the massive Shantungosaurus or “Shant” for short. While Triceratops and Stegosaurs can hold their own against a large apex, so too can Shants, and perhaps more easily. These herbivores like to travel with herds of other hadrosaurs, avoid any and all ceratopsians, and are aggressive to anything else that could be a threat. They will tolerate most small herbivores, but almost everything else is threatened with calls, mock-charges, and stomps. Due to this, hadrosaur herds love grouping with these larger cousins as they offer amazing protection from almost any major threat.

During mating season, males will compete for the right to mate by bellowing and beating at one another until one backs down. Females will all work together to communally raise their young, while males stand guard and bully away threats. If truly large threats arise, the whole herd will move to protect their young, placing themselves between the predators and their children. Due to the large size difference, these creatures don’t typically see humans as a threat, but one should still be careful to not stray too close to their young, or they’ll find themselves crushed beneath their powerful feet.

• Can herd and nest with any herbivore.

• Bullies that are known to food and water hog.

People might think the Stegosaurus would be slow for its size, and those people would be wrong. “Stegos” are fairly quick creatures that can turn on a dime and bring their spiked tails to bear on anything that looks at them funny. They’re the jocks of the herbivore world. They’re loud, they’re brash, and they’re not afraid to bully and throw their weight around. They’re jerks, is basically what I’m saying. If they see a food bush or water source they want, they’ll walk over and take it with threatening calls and charges. They will also guard water or food in their immediate area until they’re finished eating or drinking as well. And if the other creature doesn’t like it, they’ll get a spiked tail up their backside to make them reconsider.

Everyone makes way for Stegos. They have to eat first, drink first, or they will swing away at anything that doesn’t let them finish first. Even most carnivores seem to steer clear of Stegos, unless they’re very hungry, very desperate, or largely outnumber them. This makes Stegos a pain for nesting creatures, as they often see fit to bully adults away from food or water, making the babies wait.

As long as most creatures keep their distance, humans included, Stegos aren’t much of an issue. Their aggression extends to nesting as well, meaning nesting Stegos are just as dangerous as nesting Triceratops. All in all, Stegos are nice to look at from a distance, but not always the thing most herds want to see up close.

• Can herd and nest with any herbivore.

• Highly aggressive while nesting, even toward other herbivores.

Therizinosaurus

• Herd Size| 6 adults + unlimited juvis.

• Nesting| Unlimited. Must leave at .6 (fresh adult) stage if the herd is full.

  • Paired| Acro Pack, Apex Pair.

  • Herd (3+)| Nothing.

Despite looking like a giantanic feathered doom-beast, the “Theri” or Therizinosaurus is actually a herbivore. Sometimes called the “Death Turkey” or just “Turkey”, Theris are incredibly dangerous dinosaurs for most predators to hunt. A small herd of three Theris don’t even budge when it comes to staring down an apex pair, if only due to their threat potential, surprising speed, and long, slender claws that make most things think twice. This is especially true if a group of Theris are nesting. They are fiercely protective and will threaten or attack anything that gets too close to the nest or young. This includes other herbivores, which makes them poor partners or traveling companions when they have young. However, if not nesting, Theris often follow behind other herbivore herds at a distance, and generally keep to themselves.

Despite having the temperament of a cranky goose, Theris enjoy herding with groups of Gallimimus or Dryosaurs, as well as the occasional Stegosaurus, Anky, or even the smaller Pachy. As the Theri is basically a massive angry goose on steroids, it is advised that any human keep their distance if only to be safe.

• Can herd with any herbivore.

• Incredibly passive and will often walk by most carnivores without aggression.

• Does not like anything going under its belly and may stomp without warning.

• If you do not move out of it's path, you may be stomped; only exceptions are nesting areas and carnivores with bodies.

Camarasaurus

• Herd Size| 4.

• Nesting| Cannot nest.

• Avoids|

  • Solo| Apex Pair.

  • Paired/Herd (3+)| Nothing.

The smaller of the two sauropod dinosaurs inhabiting Isla Nycta is the Camarasaurus or “Cama”. These creatures should be larger than any apex predator when fully grown, although, curiously, the creatures on the island appear to be smaller than their fossils would show. However, despite the difference in size, they can easily wipe out anything of their size and smaller with a few blows from their powerful tails. The only creatures daring enough to hunt these animals are a pair of Giganotosaurus, who seem to use their heavy bleeding to weaken the Cama over time with hit-and-run tactics, or the T-rex, which attempts to break the Cama’s leg. Their power, however, is rarely used, and these dinosaurs are usually gentle giants, slowly migrating across the island in search of food.

Other herbivores often enjoy the protection that a Cama can provide with its mere presence, but these creatures are incredibly rare, making such protection equally uncommon. Camas seem to enjoy standing in or submerging most of their bodies in water, as counter as one might imagine that to be due to their sheer weight making them sink into the mud. Still, these creatures, though rare, are still a sight to see for anyone on the island.

Puertasaurus

• Herd Size| 4 adults/juvi mix (only 1 herd in an area)

• Nesting| Nesting is bugged. 1 per adult female.

• Avoids| Nothing.

The largest creature that stomps across the plains of Isla Nycta is the absolutely titanic Puertasaurus. Called the “Pue” for short, these massive creatures roam the landscape looking for food and water, only stopping for short periods of time. It’s hard to know whether or not they register humans at all, much less as a threat, as most creatures of humans size, or even larger, seem to provoke no reaction from these mountains of flesh and bone.

They are wary of nothing except perhaps incredibly cocky or desperate Giganotosaurus pairs, and even then, one swipe from their tails or stomp from their legs will end a hunt in to time at all. Even the mighty T-Rex stays clear of this creature, and none truly attempt to challenge it. The Pue, however, is basically passive in nature. It casually watches other herbivores hang around it, munching on plants without a care in the world.

Passive does not mean non-aggressive, though. Anything scurrying under this massive creature’s legs, or refusing to get out of its path may find itself crushed beneath stomping feet.

All but invincible, these great beasts roam with an eternal wanderlust, seeing sights far and wide from their tall perches. While herds are rare for these animals, if seen at all, they only ever number up to four. As striking as these creatures are to see and hear, they don’t often stick around for long, often vanishing into the valleys and wilderness from whence they came, leaving all stunned in their wake.
