Episode 384 is all about Adeopapposaurus, a sauropodomorph that lived in the Early Jurassic in what is now San Juan, Argentina.
We also interview Thomas Halliday, a paleobiologist who specializes in mammal evolution and phylogenetics. His research also includes renaissance paleontology, faunal networks, and decolonizing paleontology. And he is the author of the book, “Otherlands: A World in the Making”

The dinosaur of the day: Adeopapposaurus
- Sauropodomorph that lived in the Early Jurassic in what is now San Juan, Argentina (Cañón del Colorado Formation)
- Looked like other sauropodomorphs, with a long neck, small head, long tail, walked on two legs
- Estimated to be about 10 ft (3 m) long
- Herbivorous
- Probably had a keratinous beak
- One of the first known to have a lower and upper bill
- Lower jaw was about 10% shorter than the upper jaw, which gave it a slight overbite
- Type species is Adeopapposaurus mognai
- Named in 2009 by Ricardo Martinez
- Genus name means “far eating lizard” and refers to its long neck
- Species name refers to the Mogna locality in San Juan Province, where the fossils were found
- Holotype includes a skull, vertebrae, pelvic girdle, forelimbs, and incomplete hindlimbs
- Known from four partial skeletons and two partial skulls
- Similar to Massospondylus
- First thought to be Massospondylus
- Had a gracile femur
- Had short forelimbs
- Had a “gracile and delicate” humerus
Fun Fact: Dinosaurs get through early development remarkably faster than humans.
