Episode 423: Ankylosaur and sauropod tail weapons plus a paleo controversy. Most pace of sauropod tails, ankylosaurs clubbing one another, a paper on the Tanis web site might embody pretend information, a brand new ornithopod, and the way AI is being utilized in paleontology
Information:
- One of many papers concerning the Tanis web site has been accused of getting pretend information supply
- There’s a brand new dwarf rhabdodontid dinosaur, Transylvanosaurus platycephalus supply
- Ankylosaurs in all probability developed their tails for combating one another, not for defending in opposition to predators supply
- Diplodocid tails couldn’t break the pace of sound, in keeping with a brand new mannequin supply
- Synthetic Intelligence helped remedy the thriller of dinosaur tracks in Queensland, Australia supply

The dinosaur of the day: Abrosaurus
- Macronarian sauropod that lived within the Center Jurassic in what’s now Sichuan Province, China (Decrease Shaximiao Formation)
- Most likely seemed like different sauropods, although possibly a bit extra stout, in keeping with paleoart
- Had an extended neck, lengthy tail, walked on 4 legs
- Solely the cranium has been described
- Had a extra boxy head, with a tall bony arch on prime (in entrance of the eyes) the place the nostrils have been
- Estimated to be about 30 ft (9.1 m) lengthy
- Sort species is Abrosaurus dongpoi
- Genus title means “delicate lizard”
- Genus title refers back to the cranium, that had giant openings separated by skinny bones
- Species title is in honor of the poet Su Shi, a.ok.a. Su Dongpo, who was born in Sichuan and lived from 1037-1101
- Fossils found in 1984 and first described in 1986
- First described by Ouyang Hui as Abrosaurus gigantorhinus
- However, his thesis didn’t meet ICZN requirements in order that title is a nomen nudum
- In 1989 Ouyang formally described Abrosaurus as Abrosaurus dongpoensis
- Nevertheless, “ensis” is barely used to discuss with localities so the “i” suffix was used as a substitute, to discuss with a male particular person (therefore, Abrosaurus dongpoi)
- Holotype is an almost full, effectively preserved cranium
- A fragmentary cranium and skeleton have additionally been discovered, however haven’t been described
- Had a flippantly constructed cranium (“delicate” and “swish”)
- Hui described it as a “average sized sauropod with a carefully constructed cranium”
- Additionally had “extraordinarily giant” fenestrae within the cranium
- Had a comparatively low, elongated cranium
- Had openings within the cranium much like Camarasaurus, however the cranium of Camarasaurus is extra sturdy
- Had slender, elongated nasals, that have been about one-third the size of the cranium
- Had “considerable” tooth
- Had spoon-shaped tooth
- Initially described as a camarasaurid, although that might not be the case
- Later analysis discovered it to be a basal member of Macronaria, like Camarasaurus, however wants extra analysis (comparable to the outline of the second specimen) to be extra sure
- Housed because the Zigong Dinosaur Museum
- Different dinosaurs that lived across the similar time and place included stegosaurs comparable to Bashanosaurus, Huayangosaurus, sauropods comparable to Shunosaurus, Omeisaurus, and theropods comparable to Leshansaurus, Gasosaurus, Yangchuanosaurus
- Different animals that lived across the similar time and place included Crocodyliformes, pterosaurs, and turtles
Enjoyable Reality:
Ankylosaurs might have had completely different sized tail golf equipment and extra armor relying on in the event that they have been male or feminine (AKA sexual dimorphism).
