There are only 10 animals in JP-Builder which IMO are either lame, redundant and/or unrealistically placed in their parks:
1-Nasutoceratops(why not Styracosaurus?)
2-Tuojiangosaurus(Kentrosaurus would be a better choice)
3-Suchomimus(Baryonyx and Spinosaurus are enough/better)
4-Pterodactylus(smaller pallete-swap of Pteranodon)
5-Trinacromerum(smaller version of Pliosaurus with 'meh' name)
6-Koolasuchus(a freshwater amphibian in salt-water?)
7-Gillicus(smaller palette-swap of Xiphactinus)
8-Arthropleura(biggest source of facepalms and WTFs? in JP-Builder)
9-Amebelodon(boring version of Platybelodon)
10-Archaeotherium(Entelodon and Daeodon are enough/better)
Can't say which species I would replace them with, since I have too many suggestions. As for JW-The Game... Many of the 'newcomers' I dislike(not counting hybrids). However, there are some I like, for example Dimetrodon, Postosuchus, Guanlong, Onchopristis, Xenacanthus and Liopleurodon. Of course, the game is still new and being updated, so we will have to wait and see what new animals will appear in the future.
