92	Lesothosaurus diagnosticus	Forested regions	Ornithischian	Plants, insects	Early Jurassic	Africa	~22 pounds	~1 foot	~3 feet	~100 psi	~25 mph	Lesothosaurus was a small, swift omnivore/herbivore from the Early Jurassic of southern Africa, possibly active at dusk or dawn due to its relatively large eyes.
93	Ouranosaurus nigeriensis	Riverbanks and wetlands	Ornithopod	Plants	Early Cretaceous	Africa	~4 tons	~14 feet	~25 feet	~400 psi	~15 mph	Ouranosaurus featured a sail-like structure on its back, supported by elongated vertebrae. This sail may have helped with thermoregulation or display.
94	Camptosaurus dispar	Woodlands and open plains	Ornithopod	Plants	Late Jurassic	North America	~2 tons	~5 feet	~23 feet	~600 psi	~15 mph	Camptosaurus was a transitional ornithopod capable of walking bipedally or on all fours when feeding. It bridges smaller bipedal dinosaurs and larger hadrosaurids.
95	Shuvuuia deserti	Deserts	Theropod	Insects, small animals	Late Cretaceous	Asia	~3 pounds	~1 foot	~2 feet	~50 psi	~15 mph	Shuvuuia was a tiny, nocturnal alvarezsaurid with excellent night vision and hearing, specialized in hunting insects in desert conditions. 'Shuvuuia' means 'desert bird.'
96	Alvarezsaurus calvoi	Forested areas	Theropod	Insects	Late Cretaceous	South America	~45 pounds	~2 feet	~6 feet	~100 psi	~25 mph	Alvarezsaurus was a small theropod with single-clawed forelimbs adapted for digging, possibly feeding on termites. It shows extreme limb specialization among dinosaurs.
97	Atlascopcosaurus loadsi	Coastal plains	Ornithopod	Plants	Early Cretaceous	Australia	~1 ton	~5 feet	~16 feet	~300 psi	~20 mph	Atlascopcosaurus was an Australian ornithopod named after the company that assisted in excavations. This medium-sized herbivore exemplifies dinosaur diversity on ancient Gondwana.
98	Tropeognathus mesembrinus	Marine environments	Pterosaur (flying reptile)	Fish	Early Cretaceous	South America	~200 pounds	N/A (flying)	~26-foot wingspan	~500 psi	~50 mph	Tropeognathus was a large pterosaur (not a dinosaur) known for a prominent keel on its snout.

Its long neck allowed it to browse high vegetation, and its sheer size made it one of the largest land animals of its time.
102	Patagotitan mayorum	Forested floodplains	Sauropod	Plants	Late Cretaceous	South America	~69 tons	~16–20 feet at the hips	~120 feet	~500 psi	~5 mph	Patagotitan was an enormous titanosaur that roamed the plains of South America. Its massive size and long neck made it capable of reaching high vegetation, and it is considered one of the largest creatures to have ever walked the Earth.

It likely roamed floodplains in South America, using its long neck and tail to feed on vast amounts of vegetation.
104	Sauroposeidon proteles	Lush floodplains, conifer forests	Sauropod	Plants	Early Cretaceous	North America	~50–60 tons	~20–25 feet at the hips	~115 feet	~300 psi	~5 mph	Sauroposeidon was a towering sauropod from the Early Cretaceous. Its extraordinarily long neck allowed it to reach high vegetation, making it one of the tallest land animals known.
