Before the dinosaurs, there were Triops. Fossil Triops more than 200 million years old have been discovered. By comparison, dinosaurs date back only about 60 million years...just 'youngsters' in terms of geologic time. Triops are distant relatives of trilobites. Triops means three-eyes while the name trilobite means three lobed or three segments.
A pterosaur is a winged dinosaur. They are the first of the vertebrate dino-critters that achieved powered flight.  Wikipedia has additional information, and a link is provi â¦ ded.
