Hello, I'm simply looking to buy a phytosaur tooth and I was wondering if it's authentic. The pictured tooth is from the Redonda Formation of New Mexico and Triassic in age. Thank you.

I have collected quite a few interesting fossils from the Redonda formation, and I will be posting to this thread as I take photos. Two very large vertebrae to start- likely belonging to the Phytosaur Redondasaurus.

I have gone through all of my Redonda formation teeth, and think these ones are likely theropod, possible Coelophysis. Any insight would be greatly appreciated! Tooth 1: 7mm long, serrations ~8/mm along middle of posterior edge.

Hello, I just wondered if anyone has seen something like this before. This tooth is from the Redonda formation, in Quay Co., NM. It measures 34mm long, and has a misplaced 8mm ridge of serrations, in addition to the two main edges that most teeth of this type have.

Hi. I was wondering if anyone could help me narrow down the identification of this phytosaur tooth. Is it possible to determine the genus or species from just a tooth? I think Redondasaurus may be a potential match, but it looks like there are a few archosauriforms in the Redonda formation. Thanks for any help.

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.

I found this piece of bone about a month ago and didn't really know what I was dealing with until I started prepping it out. I know that it is theropod based on the hollow structure, this should be at least somewhat visible in the photo of the broken edge. It came from the Redonda Formation in Eastern New Mexico where theropod remains have been found, but nothing identifiable to species. If anyone here can identify the species that would be fantastic, but I really just want to know what bone it is. My guess is the end of the pubis or ilium, but I was hoping for some other opinions.

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!
