From the album: Triassic
From the "dawn" of the Dinosaurs, this small tooth represents an early theropod. Unlike the other serrated archosauriform teeth present in the formation, this tooth is ziphodont - thin and labio-lingually compressed - the archetypical tooth form that most theropods adhered to since their beginnings.-

Revueltosaurus was a Pseudosuchian, on the branch of the Archosaurs more closely related to the Crocodilians than the Dinosaurs. Despite the serrated teeth, it is thought to have been herbivorous.-

Lungfish are an ancient group of fish, with swim bladders that evolution co-opted as a kind of "lung," allowing them to breathe air. This may have proven invaluable in a seasonally dry climate in Pangea.-

Hi y'all, found this partial tooth in micromatrix from the Triassic-aged Bull Canyon formation. Serration density looks to be 9-10 / mm on the dc. Could it be dinosaurian?

Hi, i just got this one, i thought it's an aetosaur spike but now I'm unsure.. it's bull canyon and 4 cm long. Does anyone here know?

I got many bags of micromatrix to sift through over the Summer, one of them being from the Bull Canyon Formation, which is Late Triassic in age (~227-208.5 Ma). As has been said many times before, not much is known about the teeth that can be found here, unfortunately. The vast majority of fossils that I've found so far are fish scales, lots of fish scales. I've found a few teeth, serrated and non-serrated (mostly partial), a couple of tooth plates/jaw fragments, and random chunks of bone. The matrix is about medium grain size. For scale, the sorting dish I'm using has 1 cm squares. Most of the rock is a red color, and the fossils are almost entirely white. Here are couple of "in situ" shots: Jaw section (fish?): Tooth plate (also fish?): Serrated tooth fragment: Non-serrated, striated tooth fragment (amphibian?): A nearly complete serrated tooth!:

Alternative combination: Leptolepis schoewei. Taxonomy taken from NMNH Catalog Number USNM V 17903. DIAGNOSIS after Schaeffer & Patterson (1984): "Middle Jurassic teleostean fishes of leptolepid grade, but differing from similar fishes in having only chordacentra until late in growth. The chordacentra receive perichordal additions only in the midcaudal region, and only in the largest specimens. About 50 vertebrae, 30 abdominal. Dorsal fin in the middle of the back with about 16 rays; anal originates beneath posterior edge of dorsal, with about 14 rays; pelvics beneath dorsal origin, with about 12 rays. No bone-enclosed rostral commissure or rostral pitline; supraorbital sensory canal not meeting infraorbital, and with three medial and two lateral branches above the rear of the orbit…." Identified by oilshale according to Schaeffer and Patterson, 1984 on the basis of the leptolepid maxilla and praemaxilla, fins and fin position, weak scaling, and absent or weak chordacentra.

I identified this fossil as a Hesperosuchus agilis tooth. It is from Bull Canyon and it measures only 3 mm. Is it a Triassic Hesperosuchus agilis tooth?

Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone formation, Texas 1 small vial of Cretaceous Lower Gault Clay, East Wear bay, Folkestone, Kent, UK A micropalaeontology slide with Jurassic Blue Lias matrix rich in holothurian material. A thin section of an Ostracods filled Elimia snail from the Green River Formation in Wyoming A thin section from the Rhynie chert of Scotland which should contain preserved parts of the plant Aglaophyton major and perhaps even other species. I also got a lot of Bull Canyon micro fossil teeth and 2 cretaceous mammal teeth from Hell Creek In this topic you will be able to follow my path through this newly discovered hobby as I will post my finds and progress Currently I am only working with a clip-on cellphone microscope, but I do plan on getting a professional microscope in the next few months! (Tips are always welcome) So let's put on our Ant-Man suit and explore the microfossil realm So here are some of the first pictures I made of some of the microfossils Starting with the thin slices! Thin slice with Ostracon filled Elimia tenara snail from the Green River Formation, Wyoming Thin slice with Aglaophyton major from Rhynie Chert in Scotland

Found these four, if someone can take a look. All from Bull Canyob. 1 - A preondactylus tooth. 5mm. Now, I know this is from Italy, so I'm guessing name is wrong. But is it pterosaur? 2 - Fabrosaurus. 3mm 3 - Prosauropod. 4mm 4 - Eudiomorphodon - 2mm. Another species I thought was from Italy. Many thanks

Building the Dinosaur Program- Bull Canyon and the maybe Triassic Dinos
fossilsonwheels posted a topic in Member Collections
On to the Dinos. As I mentioned in an earlier post, I found some helpful information here about the Triassic fossil material from Bull Canyon before we started collecting the fossils so I knew going in that some of the dinosaur stuff may not be dinosaur at all or at least it may not be the dinosaur that they are sold as. The fossils are educational so we will present them as we purchased them while noting the uncertainty in documenting our collection. We want to do what we do with the sharks and start our programs as far back in the evolutionary line as we can get. Bull Canyon gives us possible dinosaur fossils that represent very early dinosaurs. The kids will likely not know much about early dinosaurs so these fossils are important in giving us that bridge. We bought three very small, and inexpensive, "Coelophysis" teeth. One of them looks that it could be a dinosaur tooth while the other two are probably not. I found a great piece by Troodon here that outlined what to look for in Bull Canyon teeth and using his profile of what to look for from a dinosaur tooth from Bull Canyon, I contacted the dealer I bought them from. He is going to find us one that fits that profile so I feel good that we will have one or two Triassic Theropod teeth. If they are actually Coelophysis or not is not a concern. That is the species we are presenting to the kids because they are such a well known early dinosaur. The kids can learn more about them on their own and they may get really interested in early dinosaurs if we can connect them to one. It gives a an opportunity to touch on basic theropod biology and get into evolution. We also got a small and inexpensive "Prosauropod" tooth. I did know before buying it that no diagnostic prosauropod fossils had been found in Bull Canyon. I can accept that this one is unlikely to be prosauropod but we are still going to present it as one because the kids will really enjoy hearing about the forerunners of the very well known Long necks. I do not have all the science info set for this part of the presentation. I am still learning about early dinosaurs. I do not think we will be able to add much to this part of the dinosaur program. There does not seem to be a lot of fossil material available so i think this will have to be enough. Pic 1 our tiny collection of tiny Triassic "dinosaur" teeth.

Was wondering if anyone could help confirm the identity of this vertebra
-
I recently obtained a mixed lot of Bull Canyon teeth, which is a formation I'm unfamiliar with. I was wondering if Coelophysis teeth have certain features that one can look for to confidently assign them to this taxon? Are there any other species commonly confused with Coelophysis? It seems many of the ones for sale online being sold as Coelophysis may not actually be. Any advice is welcomed!

Hello all, I just picked up this pretty vert and am not quite sure about the ID. The seller advertised it as Coelophysis, but it doesn't seem to be a match. It's from Bull Canyon formation, Quay County, New Mexico (Upper Triassic). It measures 2 1/2". The seller provided good pictures, so I've attached some of those. I can provide more and even take some of my own if needed! Thanks, and hopefully we can figure out an ID on this one!
