Episode 410: A brand new tyrannosauroid that was smaller than Moros, however larger than Suskityrannus; plus a brand new therizinosaur from Hokkaido; and a examine of the comfortable pads on sauropod toes
Information:
- A brand new unnamed tyrannosauroid was found in Idaho which was smaller than Moros, however larger than Suskityrannus supply
- There’s a brand new therizinosaur named Paralitherizinosaurus that was present in Hokkaido, Japan supply
- A brand new specimen of Yulong mini was discovered, which helps present how the dinosaur grew because it aged supply
- Sauropods could have developed comfortable tissue pads on their toes by the Late Triassic to Early Jurassic, and this may increasingly have been a key adaptation for them to evolve into giants supply

The dinosaur of the day: Patagosaurus
- Eusauropod dinosaur that lived within the Early–Center Jurassic in what’s now Patagonia, Argentina (Cañadón Asfalto Formation)
- Seemed like different sauropods, with a protracted neck, small head, lengthy tail, and walked on 4 legs
- Estimated to be about 54 ft (16.5 m) lengthy and weighed about 7.88 t (different estimates that it was about 46 ft or 14 m lengthy)
- Fossils discovered within the Nineteen Seventies
- Holotype included an almost full skeleton (no cranium)
- A number of specimens discovered, so we all know virtually the entire skeleton, together with the cranium
- Cranium not well-known, principally the jaws are recognized
- Lot of specimens discovered (initially 12, however now could solely be 11, based mostly on a redescription of Patagosaurus which discovered one specimen could also be a special taxa/dinosaur)
- A minimum of one juvenile discovered
- Femke M. Holwerda and others redescribed Patagosaurus in 2021
- Herbivorous
- Had a mixture of basal and derived sauropod traits (previous and new). One derived trait is the air-filled cavities in bones (pneumatization), which made the bones lighter
- Had gracile (slender) forelimbs in comparison with later sauropods like Camarasaurus
- Had tall neural spines
- Had 5 sacral vertebrae (in between the hips)
- Had “saddle” formed neural spines on the entrance tail vertebrae (anterior caudal vertebrae)
- Had a comparatively quick, excessive decrease jaw (dentary)
- Had a brief, excessive, broad snout
- Enamel much like Camarasaurus (spoon-shaped)
- Had a lot of alternative tooth
- In all probability changed tooth each 58 days
- Juveniles appeared somewhat completely different from adults. For instance, grownup femora (leg bone) had completely different proportions from juveniles
- Additionally attainable that juveniles had fewer tooth than adults
- Lengthy neck could have helped with avoiding over-heating
- Described by Jose Bonaparte in 1979
- Sort species is Patagosaurus fariasi
- Genus identify means “Patagonia lizard”
- Genus identify refers to being a reptile present in Patagonia
- Species identify in honor of Ricardo Farias, who owned the farmland the place the fossils had been discovered
- Lived in a heat, humid local weather
- A lot of conifers and ferns
- Different dinosaurs that lived across the similar time and place embody Piatnitzkysaurus (megalosauroid), Condorraptor (megalosauroid), Volkheimeria (eusauropod)
- Different animals that lived across the similar time and place included amphibians, turtles, mammals
Enjoyable Truth:
73% of the rock uncovered on Earth is sedimentary rock (the perfect for locating fossils) however sadly it doesn’t all protect fossils.
