Isaberrysaura mollensis

Name: Isaberrysaura mollensis 

Name Meaning: Isabel Berry’s Reptile 

First Described: 2017

Described By: Salgado et al. 

Classification: Dinosauria, Ornithischia, Genasauria, Thyreophora?, Eurypoda?, Stegosauria? 

Thanks to a scheduling error, today we’re going to talk about one of the more mysterious dinosaur discoveries of the past two years - Isaberrysaura! This dinosaur was found in the Los Molles Formation of Neuquén, Argentina, living somewhere between 175 and 169 million years ago, from the Toarcian age of the Early Jurassic to the Bajocian of the Middle Jurassic. This is actually a marine formation, meaning the body of this animal probably washed out to sea, though it probably did live near the coast as that part of the environment is a portion of the formation. It is a weird dinosaur because, originally, it was thought to be a Neornithischian - similar to Kulindadromeus. These animals are distinctive for having thickened enamel, and at least in the basalmost forms, having shortened and round skulls. Isaberrysaura, on the other hand, has a very long and narrow skull, much like a stegosaur. This would have made it a specialist feeder, eating solely on those specific plants it wished to, rather than browsing indiscriminately. It has similar skull features, besides shape, to basal stegosaurs, which increases the weirdness at hand. It also has different types of teeth. It was preserved with fossilized stomach contents including lots of seeds from cycads, and they were swallowed whole, with no chewing taking place. Isaberrysaura probably had a mixed diet, but only the mixed seeds are known. The fossil was not found with plates, but also wasn’t found with limbs or the tail, and later phylogenetic analyses have found it to be the basalmost known Stegosaur - so perhaps even a transitional form between early Thyreophorans and the Stegosaurs - though more remains and study of this animal are needed to truly piece together the mystery.

Tiny New Species of Stegosaur Unearthed in China

Tiny New Species of Stegosaur Unearthed in China

The newly discovered fossilized stegosaur found in China is the now ancient ever found in Asia, and could be the oldest in the world. Treading the Earth some 170 million years ago, during the Middle Jurassic Bajocian age, the beastie was also small for a stegosaur, measuring just 2.8 meters (just over 9 feet) from its nose to the tip of its spiny tail; larger stegos could grow up to 9 meters…

Agrosaurus

Agrosaurus (/ˌæɡroʊˈsɔːrəs/; Greek agros meaning 'field' and sauros meaning 'lizard', "field lizard") is the name given to the remains of what was originally believed to be a Triassic prosauropod from Australia. Agrosaurus would thus be the oldest dinosaur from that country. However, this appears to have been an error, and the material actually appears to come from Thecodontosaurus or a Thecodontosaurus-like animal from Bristol, England. The type species is Agrosaurus macgillivrayi. Members of an expedition from the British sloop HMS Fly supposedly collected a tibia, a claw and some other fragments in 1844 from Cape York, Queensland. The original block was purchased by the British Museum of Natural History in 1879, but the remains were not studied until 1891. Harry Govier Seeley in that year named it Agrosaurus macgillivrayi. The block was prepared in the late 1980s. Following the preparation, Ralph Molnar (1991) noticed similarities to the prosauropod Massospondylus. Galton and Cluver (1976) saw Agrosaurus as close to Anchisaurus. Vickers-Rich, Rich, McNamara and Milner (1999) equated Agrosaurus and Thecodontosaurus antiquus, claiming that the British Museum remains were mislabelled. The difficulty in correctly identifying the source of the fossil lies in the fact that the log of the Fly does not record it. The matrix in which the prosauropod bones were preserved was tested with rocks of similar age in Cape York and Durdham Downs, the latter being beds where Thecodontosaurus remains have been found in the Bristol area of England. The English beds compared most favourably. In fact, as early as 1906 Friedrich von Huene had described the rock matrix as 'extremely reminiscent of the bone breccia at Durdham Downs near Bristol' and had renamed the species Thecodontosaurus macgillivrayi. Remains of the jaw of a sphenodont identical to Diphyodontosaurus avonis, a lizard-like reptile common to the Bristol Triassic beds have been extracted. This reinterpretation of Agrosaurus as a misidentified British specimen has been accepted in later works. From the scant remains the living animal would appear to have been about three metres long (10 ft), with a typically prosauropodan appearance: bulky body, long neck, small head and clawed feet.[citation needed] Like other prosauropods, it was probably equally comfortable on all fours as well as on its elongated hind legs. It was herbivorous or may have been an omnivore. The name Agrosaurus is now generally considered to be a nomen dubium or a junior synonym of Thecodontosaurus. If Agrosaurus is not from Australia, which seems most probable, Rhoetosaurus and Ozraptor, both from the Bajocian (Middle Jurassic) would be the oldest known Australian dinosaurs. Fortunately they are well documented. More details Android, Windows

6.5" Strigoceras truellei Fossil Ammonite – Niortense Zone, Middle Bajocian, Jurassic: West Bay, Burton Bradstock, Dorset, UK – Alice Purnell Collection –

This listing features a superb 6.5-inch fossil ammonite of the species Strigoceras truellei, sourced from the Niortense Zone of the Middle Bajocian Stage in the Jurassic Period, approximately 170 million years ago. It was found in the fossil-rich coastal cliffs of West Bay / Burton Bradstock, Dorset, United Kingdom, a site that forms part of the globally renowned Jurassic Coast, a UNESCO World Heritage Site.

Strigoceras truellei is a distinctive ammonite species within the family Strigoceratidae, known for its finely ribbed, compressed shell and involute whorls. These ammonites thrived in the shallow tropical seas of the Jurassic and were part of a vibrant marine ecosystem dominated by invertebrates and early marine reptiles.

Geologically, this specimen originates from the Inferior Oolite Group, a Middle Jurassic limestone sequence formed from sediments deposited in warm, shallow marine environments. The Niortense Zone, in particular, is a key biostratigraphic marker within the Bajocian and has yielded some of the most visually striking and scientifically valuable ammonite specimens.

This beautiful ammonite comes from the distinguished Alice Purnell Collection, a highly regarded assemblage of scientifically important and visually exceptional fossil specimens gathered over decades. The fossil has been professionally cleaned and stabilised, ensuring it is display-ready and suitable for both scientific interest and aesthetic appreciation.
