Most (if not all) of the animals in the first installment are in the sequel, but I already made a post about those. https://dinopedia.fandom.com/f/p/4400000000000124217

Casuarimimus. Caenagnathidae. 3.5 meters long.

Colossoceratops. Ceratopsidae. 6.5 meters long.

Titanospinus. Spinosauridae. 16 meters long.

Nanodromaeus. Thescelosauridae. 2.5 meters long.

Sauropotamus. Iguanodonitdae. 7 meters long.

Velocivenator. Troodontidae. 2.5 meters long (without tail feathers)

The number of named species in this series (not including the ones that are just normal animals) has gone from 16 to 29! There could have been a 30th one, but I couldn't find a good skeletal diagram for a Champsosaur.
