Mesozoic Species and Groups that Should Be Brought Back from Extinction


The Top Ten

1 Troodon Troodon

These dinosaurs were actually not as dangerous as humans may think, as they filled an omnivorous niche similar to modern foxes, so they rarely attack animals larger than themselves, as foxes do in modern times. They could also adapt really well in a life in a city in a similar manner to foxes, and if they adapt to deal with predation and eggs being eaten by modern predatory and egg-eating mammals, Troodons would flourish. - DinoLover4242

2 Plesiosaurs Plesiosaurs

Plesiosaurs had a unique swimming fashion that not even sea turtles have in modern times, so by bringing any species of Plesiosaurs back from extinction, we could finally study what they look like, what they eat, and how they swim. Maybe due to popular demands, some people may introduce some non-invasive Plesiosaurs into modern oceans, they may adapt to deal with marine mammals they would eventually co-exist with. - DinoLover4242

3 Ichthyosaurs Ichthyosaurs
4 Compsognathus Compsognathus

A lot of people would love to have these small chicken-sized non-avian theropods as pets. - DinoLover4242

5 Microraptor Microraptor

A lot of people would love to have these small pigeon-sized non-avian theropods as pets. - DinoLover4242

6 Sinornithosaurus Sinornithosaurus
7 Oviraptor Oviraptor
8 Therizinosaurids Therizinosaurids
9 Ornithomimids Ornithomimids
10 Leedsichthys Leedsichthys

The Contenders

11 Epidexipteryx Epidexipteryx
12 Scansoriopteryx Scansoriopteryx
13 Yi Qi Yi Qi
14 Deinonychus Deinonychus
15 Coelophysis Coelophysis
16 Velociraptor Mongoliensis Velociraptor Mongoliensis

Should be brought back, since in reality, Velociraptors are wolf/turkey sized, they do NOT have pronated hands (so they couldn't open doors), their snouts are elongated, and they're covered in thick feathers (including fan feathers on their tails and wing feathers on their arms), so they look like flightless birds with toothy snouts, clawed fingers, and long bony tails, so they look nothing like how Jurassic Park and Jurassic World portrayed them, and they were only about as smart as canines. Maybe if the REAL Velociraptors were resurrected successfully, maybe more people will learn about real Velociraptors instead of just looking at Jurassic Park raptors. - DinoLover4242
