Stegosaurs (four legged, large fins on back ridge, spiked tail) was from the Jurassic; Triceratops (four legged, one horn above each eye, horn above nose, neck frill) was from the Cretaceous; Ankylosaurus (four legged, clubbed tail, bony armor like a turtle on back) was IIRC late Jurassic / early Cretaceous...

Stegosaurus's we can use them for open air urban buses like in the Flintstones!🤣
