Biomedical Ephemera, or: A Frog for Your Boils

@biomedicalephemera / biomedicalephemera.tumblr.com

A blog for all biological and medical ephemera, from the age of Abraham through the era of medical quackery and cure-all nostrums. Featuring illustrations, history, and totally useless trivia from the diverse realms of nature and medicine. Buy me a coffee so I can stay up and keep the lights on around here!

Check out these awesome dinosaurs. All pretty and baller and songbirdy and stuff!

Yup, birds are dinos. There are “avian dinosaurs” (Saurischia), which have hips that have legs sticking straight out underneath them, and “non-avian dinosaurs” (Ornithischia - confusingly, translates as “bird-hipped”), which have legs that splayed out to the sides. Birds first appeared during the Jurassic period, 150 million years ago, and they’re the only surviving member of the Dinosauria clade.

All carnivorous dinosaurs were warm-blooded, and were Saurischians. One of the two primary herbivorous dinosaur lines is also Saurischian - the Sauropodopmorpha (including Apatosaurus, Diplodocus, and Argentinosaurus) branched off around 230 mya, but well-known dinosaurs such as triceratops and stegosaurus are comparatively unrelated to modern birds.
