The dinosaur of the day: Asylosaurus
- Basal sauropodomorph that lived within the Late Triassic in what’s now Clifton, Bristol, England
- Walked on two legs and had a protracted tail
- Had brief neural spines
- Estimated to be about 6.7 ft (2 m) lengthy and weigh 55 lb (25 kg)
- Fossils present in 1834. Fossils embody a part of the torso, again vertebrae, ribs, gastralia, shoulder girdle, humeri, a part of the forearm, hand (extra bones referred to Asylosaurus embody bones from the neck, tail, pelvis, arm, and leg, and will belong to the holotype)
- Described in 1836 by Henry Riley and Samuel Stutchbury, initially as Thecodontosaurus
- An outline of the fossils in 1836 stated they had been obtained by Capt. Cautley, and “discovered partly mendacity on the slopes among the many ruins of fallen cliffs, and partly in situ within the sandstone”
- OC Marsh introduced the fossils to Yale College between 1888 and 1890
- Survived WWII (the holotype of Thecodontosaurus was destroyed in 1940 throughout the Bristol Blitz)
- Described as Asylosaurus in 2007 by Peter Galton
- Sort species is Asylosaurus yalensis
- Genus identify means “unhurt or sanctuary lizard”
- Genus identify refers back to the fossils not being destroyed in WWII
- Species identify refers to Yale
- Galton discovered the fossils had three autapomorphies to be its personal genus (variations within the deltopectoral crest, humerus/manus, and ischia)
- Additionally had some plesiomorphic (ancestral traits) like basal sauropodomorphs, just like the construction of the manus and humerus, and the form of the braincase
- In 2020 Antonio Ballell and others redescribed Thecodontosaurus antiquus based mostly on new materials present in Tytherington, England
- Mentioned “the questionable validity of Asylosaurus yalensis”
- Mentioned the deltopectoral crest autapomorphy wasn’t legitimate as a result of most Thecodontosaurus and Pantydraco (previously Thecodontosaurus) specimens had incomplete crests, and the tip of the crest is prone to being distorted from taphonomy. Subsequently, the autapomorphy in Asylosaurus may very well be due to the way in which it was fossilized
- Identical difficulty with the humerus, plus the way in which the manus appears in Asylosaurus is much like different basal sauropodomorphs like Eoraptor and Sarahsaurus
- Mentioned the third character was “based mostly on ischium fragments that had been tentatively referred to Asylosaurus, with none proof”
- Concluded not one of the three characters had been sufficient for Asylosaurus to be a legitimate genus, and stated Asylosaurus yalensis was a “taxon of extremely questionable validity”
- Additionally doubted the validity of Pantydraco
- Different animals that dwell across the similar time and place embody theropods, phytosaurs, sharks, fish, crocodylomorphs, lizards
Enjoyable Reality:
There’s a Nanotyrannus equal of Tarbosaurus (330). Stegosaurus had alternating plates however different stegosaurs have been discovered with pairs of plates (334).
