Hello, I found this last year during a fossil hunting trip in the Bendricks, South-Wales. I know their are several track ways and some 200+ footprints embedded within the rock around the local areas, however I have not seen a footprint cast from this locality either (that I know of). I have tried finding a contact for the geology department at the national museum based in Cardiff, though it has been unsucessful. Any light you can shed on this would be much appreciated! It may be just a conveniently shaped rock, however it is always worth asking. Apologies for the picture, I've had to rely on someone else for the picture - it is slightly larger than than palm size. Local rocks are Triassic - approx 220 million years

From the album: Dinosaurs and Reptiles
Partial skeleton of a Middle Triassic marine reptile Anarosaurus (relative of Keichousaurus) from Muschelkalk, Germany. B, C, F, G, H - close-ups of various limb bones and vertebrae D - 2 Anarosaurus teeth E - fish scale I - Nothosaurus mirabilis (?) tooth The last two finds make me think that it is actually a Nothosaurus coprolite with digested Anarosaurus remains and various fish scales. -

Wushaichthys exquisitus Xu, Zhao & Shen, 2015 Middle Triassic Ladinian - early Carnian Falang Formation Zhuganpo Member Wusha near Xingyi Guizhou Province PR China Length 5cm -
Taxonomy from Schweitzer et al. 2014. Quote (Schweitzer et al. 2014, p. 457): "Although the lobsters were interpreted as having relatively durable cuticle, the shrimp discussed herein are characterized by having very thin cuticle that is readily deformed and oriented in a variety of positions. As a result, the description and interpretation of the morphology of the shrimp is, of necessity, a composite of several specimens; however, fine detail of many parts of the skeletal anatomy is exquisite." Diagnosis from Schweitzer et al. 2014, p. 467: "Carapace longer than high; rostrum very long, 40 percent length of carapace, with one basal suprarostral spine and one subrostral spine at midlength; uropodal exopod with diaeresis; ventral lateral margins of telson with setal pits, appearing to extend entire length of telson; third maxilliped about as long as first and second pereiopods, with spine bases or setal pits along propodal and dactyl ventral margin; pereiopods 1– 3 chelate, third pereiopod longest, fourth and fifth longer than first and second, pereiopods without spines; pleopods apparently with multiarticulate flagellae." Identified by oilshale using Schweitzer et al. 2014. Characteristic is the extremely long rostrum, constituting 40 percent of the carapace length.

Block with several Cochloceras suessi MOJS., a heteromorph ammonoid of the late Triassic Rhaetian stage. The size of the gastropod shaped ammonoids is 3-4cm. Other visible ammonoids are Arcestes sp. and Megaphyllites sp. -
From the album: alpine triassic Ammonoids
Upper Carnian/Tuvalian ammonoid fauna from the historical location/ditch on Vordersandling. The shown ammonoids come from a small lense that was found by me several years ago. No coarser ribbed Projuvavites was found only Juvavites bacchus MOJS. Therefore I range this fauna to the dilleri Zone. Tropites aff. subbullatus, Paratropites sp., Discotropites sp., Megaphyllites sp., Sandlingites cf. oribasus and Arcestes sp. -
Originally named Sinosaurichthys by Wu et al., 2011, the genus was reranked as Saurichthys by A. Tintori (2013) Diagnosis from Wu et al. 2011, p. 595: "Medium−sized Sinosaurichthys (standard body length ranging from 270–470 mm) with unusually elongated median fins with relatively few segments of fin rays; less number of neural arches between opercle and caudal fin (approximately 157–172), less number of anterior ones with neural spines (130–146); and less number of mid−dorsal scales in front of dorsal fin (69–86) than in type species; 14–15 distinct haemal spines in caudal region; pectoral fin triangular shaped with length about 1/3 of mandible length (shared with S. minuta described below); posttemporal−supracleithrum from either side separated from each other by anterior mid−dorsal scales (shared with S. minuta described below); cleithrum plate (depth/length ratio ca. 1.2–1.25) much lower than in type species (approximately 1.8), but close to that in S. minuta (ap− proximately 1). Fin formula: P 18–19, V 18–20, D/A 44–49/ >40–48, C 37–39/37–39." Identified by oilshale using Wu et al. 2011. References: Wu, F.X., Sun, Y.L., Xu, G.H., Hao, W.C., Jiang, D.Y., and Sun, Z.Y.

This is my first post, so please bear with me. I found this tooth this summer in the Rendonda formation in Quay county New Mexico. This should date it to the late Triassic, 202-204 mya. The area where it was found contains almost exclusively Phytosaur fossils, but I am 99% certain that this one is not. It measures about 2.5 cm in length and has one edge with fine serrations. Based on the general shape and serrations, I am guessing some sort of theropod, however I do not know enough about other crocodilian species such as Postosuchus to rule something like that out. Any help would be appreciated, and if you need more pictures/information, feel free to let me know!
