This mod is more of a smaller one and is going through some updates but it does add 10 new dinosaurs that I haven't seen in any other Minecraft mods:

Euoplocephalus, Chasmosaurus, Sigilmassasaurus, Alioramus, Prognathodon, Augustopholus, Alamosaurus, Telmatosaurus, Jaxartosaurus and Huaxiaosaurus.


I do plan to update this mod because there were a few things obviously wrong like Prognathodon is spawning on land for some reason and some of the Dinosaurs aren't as big as I hoped but I will get on it and release the update possibly within the week.
