Hi everyone. I found strange leaf. Leaf venation is unusial. Can it be somebody's wing? Length 53 mm. Russia, Chelyabinsk region. Late triassic or early jurassic.

A new paper is available online: Oliver W. M. Rauhut; Femke M. Holwerda; Heinz Furrer (2020). A derived sauropodiform dinosaur and other sauropodomorph material from the Late Triassic of Canton Schaffhausen, Switzerland. Swiss Journal of Geosciences 113 (1): Article number 8. doi:10.1186/s00015-020-00360-8. Schleitheimia is the first latest Norian-Rhaetian sauropodiform to be described from mainland Europe (Camelotia is a sauropodiform, but comes from the British Isles), considering that Triassic sauropodomorph cladistic diversity from Central Europe was thought to be depauperate. Therefore, it is possible that a number of indeterminate sauropodomorph remains from the Late Triassic of Germany or France could be from either Schleitheimia or another massopodan clade, like Riojasauridae or Massospondylidae. The authors of the Schleitmheimia paper also note that Gresslyosaurus ingens is distinct from Schleitheimia, while agreeing with Moser (2003) that Gresslyosaurus is a distinct genus from Plateosaurus.

Hi, If anyone is familiar with dinosaur names, the sauropodomorph informally known for a long time as "Thotobolosaurus" has been finally described and named in this paper: Claire Peyre de Fabrègues; Ronan Allain (2020). Kholumolumo ellenbergerorum, gen. et sp. nov., a new early sauropodomorph from the lower Elliot Formation (Upper Triassic) of Maphutseng, Lesotho. Journal of Vertebrate Paleontology in press: e1732996. doi:10.1080/02724634.2019.1732996. Kholumolumo is the latest addition to an increasing number of sauropodomorph taxa from the lower Elliot Formation of southern Africa that have been either revalidated or newly described in the past 15 years. Until the work of Adam Yates, it was thought that lower Elliot sauropodomorph diversity was represented by three genera, Euskelosaurus, Melanorosaurus, and Blikanasaurus. However, Yates recognized that Eucnemesaurus (long thought to have been a synonym of Euskelosaurus) is a close relative of Riojasaurus and not a synonym of Plateosauravus (which Yates revalidated for diagnostic remains synonymized with Euskelosaurus after judging the Euskelosaurus type material undiagnostic), and the renaming of 'Melanorosaurus' thabanensis as Meroktenos along with its provenance being lower Elliot rather than upper Elliot as stated in the original description by Gauffre (1993) makes clear than lower Elliot sauropodomorph diversity is way greater than previously thought. That said, could anyone send me a copy of the above mentioned paper?

Date of Trip: June 2018 Location: Quay Co., NM, USA Age: Late Triassic Formation: Redonda This was the second of a number of hunting trips across the country this summer (the first was Silex, MO, reported earlier). This will be the Triassic Vertebrate report from this trip. Triassic invertebrate report will have to wait (perhaps exciting news ). Triassic plants and Cretaceous inverts from the same general locality will also be reported later. These are finds from a coarse-grained fluvial deposit rich in fish remains. In one layer, ganoid fish scales were almost as abundant as the mineral clasts. Here is a view looking down on the bedding plane showing the fish scales laying on top: Here is the same chunk of matrix cut across the bedding planes (i.e. in side view) showing numerous scales in transverse section: Disaggregation of the matrix and rinsing through a sieve yields numerous small, complete scales (scale in mm): Large scales are present in the matrix but heavily fractured and very difficult to extract intact.

This skull will need to be prepared to find out what it is. It looks a bit too narrow to be from Diplurus newarki, (although, it could be) . It could also possibly be from the early ray finned fish, Turseodus sp. or Synorichthys sp., which are known from the same strata. Newark Supergroup, Newark Basin, Late Triassic, Lockatong Formation.

Apachesaurus amphibian vertebra Bull Canyon Formation, San Miguel County, New Mexico Late Triassic (~237 - 201.3 million years ago) Apachesaurus was a member of the Metoposauridae group of temnospondyl amphibians, though one that was particularly small. The larger close relatives of Apachesaurus include Metoposaurus and Koskinonodon which could grow up to two and a half to three meters long. Apachesaurus however grew only to around just over forty centimetres long. Due to the smaller size, Apachesaurus were probably predators of smaller aquatic organisms. Like other related genera, the eyes were placed further forward on the skull that those of other temnospondyl amphibians. Fossils of Apachesaurus are particularly well known from the states of Arizona and New Mexico where individuals have been found in concentrations. This seems to be a recurring theme that Apachesaurus shares with its relative genera, and the explanation is that metoposaurids were not very good at walking on land, so when pools of water and rivers dried out, they were left exposed to the air where they too dried out and died from lack of water.

Dear Guys, I recently found one plate like tooth in dolomite erratic, probably Late Triassic age. It is 6 mm length and has rough texture that is not typical to chimaeroids. I guess it could be mouth plate of sturgeon (its mouth opens when four plates spread in the sides) but I did not find information about isolated these elements. Some very similar teeth are shown in interent pictures and are dating by Early Jurassic: http://www.darwincountry.org/explore/005818.html?CatAdd=5818&sid= Please help to identify this specific taxon of fishes with the same appearance of teeth, I think it belongs to actinopterygians. Best Regards Domas

Dear Guys, I recently found the triangle bone in dolomite erratic of Varena town, South Lithuania, it is 4 mm length. It has the wider growths in the lower sides and straight blunt bony growth in the top. The dolomite also has poorly visible calcified lenses (maybe oncolites?). The erratic is typical to Triassic arid conditions and should belong to Late Triassic epoch because frogs from Early Triassic are found only in Madagascar island. Here is the link in frog omosternum: http://scienceblogs.com/tetrapodzoology/2010/08/27/blombergs-toad-and-buddies/

Coelophysis Dinosaur tooth fossils SITE LOCATION: Bull Canyon Formation, Dockum Group, San Miguel Co., New Mexico TIME PERIOD: Late Triassic (203-196 Million Years Ago) Data: Coelophysis is an extinct genus of coelophysid theropod dinosaur that lived approximately 203 to 196 million years ago during the latter part of the Triassic Period in what is now the southwestern United States and also in South Africa and Zimbabwe. Coelophysis was a small, slenderly-built, ground-dwelling, bipedal carnivore, that could grow up to 3 m (9.8 ft) long. Coelophysis is one of the earliest known dinosaur genera. Scattered material representing similar animals has been found worldwide in some Late Triassic and Early Jurassic formations.

Footprint? New Jersey Late Triassic/Early Jurassic Continued
Kurufossils posted a topic in Fossil ID
Hello, this is a part 2 of my last thread with some of my other finds that I've found this at a site in new jersey where some footprints have been found from the Late Triassic/Early Jurassic, I am unsure about if these are footprints of sorts, any help will be appreciated thank you!.thumb.jpg.199bfe7f0722cff28ed302cdfb98578d.jpg)

A new amphibian-related paper is available online: Jason D. Pardo; Bryan J. Small; Adam K. Huttenlocker (2017). Stem caecilian from the Triassic of Colorado sheds light on the origins of Lissamphibia. Proceedings of the National Academy of Sciences of the United States of America. in press. doi:10.1073/pnas.1706752114. The discovery of Chinlestegophis is a groundbreaking development in recording the early evolution of extant amphibians because it not only fills a gap in the fossil record of early lissamphibians but also throws a wrench into the hypothesis of a temnospondyl origin of lissamphibians by recovering major groups of stereospondyls as sister to Caecilia and Gerobatrachus as closely related to frogs, toads, and salamanders. Literally, the patchy record of Triassic lissamphibians is part of the reason why there has been disagreement over whether lissamphibians are descended from lepospondyls or temnospondyls. Therefore, the textbook on early lissamphibian evolution has to be rewritten.

Hi all, Maybe this find is past identification due to erosion, but i thought it may be of interest to others Length is around 8 inches I can see similar lines to the shell / tail feature on the right of the 'solid' part.. Wondering if anyone has any idea what it might be? is it two separate fossils perhaps? All the best Ben
