1 week ago - The first stem-group birds appeared during the Jurassic, evolving from a branch of theropod dinosaurs. Other major events include the appearance of the earliest crabs and modern frogs, salamanders and lizards. Mammaliaformes, one of the few cynodont lineages to survive the end of the Triassic, continued to diversify throughout the period, with the Jurassic seeing the emergence of the first crown group mammals.

Why is the Jurassic period the one most popularly associated with dinosaurs, when most of the most recognizable dinosaur species are from the Cretaceous?
Which species do you consider most popular? Because aside from T-rex, the dinosaurs that immediately come to my mind are jurassic. Diplodocus, other sauropods, stegosaurus, allosairus, ceratosaurus... it's been some time since I left my childhood dinosaur obsession so I might remember it wrong tho. More on reddit.com

Is there anything that can be said about the Jurassic period which marks it as distinct and more impressive than the Cretaceous?
The Jurassic is literally known as the Golden Age of the dinosaurs... I have no idea why my comment is downvoted. If I'm FACTUALLY wrong about something, then it would be nice if someone were to correct me instead of just saying that I am wrong. More on reddit.com

r/Paleontology on Reddit: Why is the Jurassic period the one most popularly associated with dinosaurs, when most of the most recognizable dinosaur species are from the Cretaceous?
April 23, 2024 -

I know the easy answer is "Jurassic Park," but that's just begging the question, since clearly Jurassic Park also got the idea from somewhere that Jurassic = dinosaurs, even though most of the species in the film/book are also Cretaceous species.

The most plausible answer I can come up with with no historical backing is that it's because Mary Anning and the other early paleontologists who founded the field in the early 1800s were digging primarily in Jurassic sites, so most of the finds that entered the public consciousness were Jurassic species, and that name just kind of stuck in people's minds as a synecdoche for the genera of animals being found. Is this the case, or is there more at play to the story that I'm not aware of?

The Jurassic Period
Great plant-eating dinosaurs roaming the earth, feeding on lush ferns and palm-like cycads and bennettitaleans … smaller but vicious carnivores stalking the great herbivores … oceans full of fish, squid, and coiled ammonites, plus great ichthyosaurs and long-necked plesiosaurs … vertebrates taking to the air, like the pterosaurs and the first birds. This was the Jurassic Period, 199.6 to 145.5 million years ago* — a 54-million-year chunk of the Mesozoic Era.
