Those things aren't dinosaurs.

The models aren't mine, but the creator gave me permission to upload them to CurseForge, so here are these creepy creatures.

Update

7 new dinosaurs were added.

Pachy Headless

A headless dinosaur that wanders aimlessly through the world; it appears in the taiga, the savanna, and the forest.

Ceratossaurus

This strange creature is a mutated dinosaur that witnessed the worst of humanity; it appears in the jungle, the taiga, and the forest.

Doomsdaysaur

This experiment spiraled out of control and created this extremely aggressive dinosaur; it will inhabit the plains, the taiga, and the jungle.

Twisted Spinosaurus

This dinosaur was once a human; now it lives in eternal pain and reacts with aggression, wandering through suffering across plains, taigas, and jungles.

The Revived One

This monstrosity was created from a dead dinosaur; what drives it is unknown, but it is extremely dangerous. It will roam the taiga and the plains, as well as the caves.

Monstrum

It is no longer known what this creature was—human or otherwise—after having interbred with a dinosaur; it roamed through swamps, plains, the taiga, and caves.

Aberrator

It is an aberration; two other heads have grown on its body, possessing minds of their own, and it wanders through the jungle, the taiga, and the forest.

Cemtiptedon

This pterosaur was controlled by a parasite that emerges from the tail and roams the plains, taiga, forests, and caves.

Decaysaurus

This dinosaur feels no pain and knows no fear, and it is not alive; yet something within drives it to rise, and it wanders through the jungle, the plain, and the forest.

Diablosaurus

This Carnotaurus underwent unexpected growth and possesses very long horns; it is extremely aggressive and roams the desert, badlands, mega taiga, plains, and savanna.

Flayed Tyrant

This tyrannosaur was unable to properly develop its skin and lost it as it grew; it wanders the plains, the taiga, and the jungle.

Gremclaw

The origin of this dinosaur is unknown; it is a strange creature that appears at night in various forests.

This add-on is mainly intended for setting the mood or for use alongside others, but I hope you enjoy it.
