Hi everyone, I've been struggling to find a way to display three associated Desmatosuchus sp. spikes from the Bull Canyon Formation, New Mexico. I decided to try using polymer clay but the block was very tough to manipulate. I'm also not 100% sure that it's safe to use in direct contact with a fossil due to the oil nature of it but I'm assuming once hardened it should be fine. My next concern is to ensure any accidental jostling doesn't cause the fossils to fall out. I've had mixed results with sticky tact; it eventually melts into some goo over time. Does anyone have any recommendations for a light, non-damaging adhesive? Or better yet, a more visually appealing display because this is kind of ugly In case anyone is curious, the other two fossils are non-associated skull fragments also from a Desmatosuchus species in Bull Canyon. And yes, I actually had to bend the primary spikes in the correct orientation on the Schleich model and sadly it's the best the figurine world has to over thus far on the enigmatic aetosaurs. I also think it's pretty cool that a set of elongated, curved back primary shoulder spikes evolved convergently at least three separate times in Desmatosuchus, the ankylosaur Sauropelta and the stegosaurian Kentrosaurus (I think there's another one that looks more like this but the name eludes me). I wonder if there's an obscure fossil turtle with some out there? Any help or suggestions are much appreciated as always! Cheers, Marcus

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?

This osteoderm was in a box of Bull Canyon Formation (Triassic - Norian) coprolites that I have been going through for the past year. The fun thing is, I one of the coprolites in this batch appears to have osteoderm inclusions that look very similar. I have looked at well over a thousand coprolites from this formation, and this is the first time I have found inclusions such as these. Needless to say, I am super, super excited!!!! Best I can figure it is from an aetosaur or phytosaur, neither of which are familiar to me. I did send an email to the person that found them to see if she is able to identify it, but thought I would throw it out to the forum at the same time. Any assistance you provide would be greatly appreciated. @Carl check it out!

Hi there, Here are 4 Aetosaur vertebrae I have from the Bull Canyon Formation, Quay County, NM. Just wondering if they are indeed Aetosaur verts? If so, can a genus be pinpointed. It has been restored and repaired; the seller found it in several pieces. Thank you! Jojo Second vertebra
