Hey everyone Would anyone here know of the most recent and up-to-date cladogram for the entire Theropoda? In what paper does it appear in? Thanks for the help. -Christian

Hello, I was out near central alberta the other day and I found two different specimens (I'll post the other one in a different thread). I doubt you'll be able to tell me what animal it came from but I was hoping the type of bone could be identified? Its heavy- so I'm pretty sure its fossilized. Its dark brown in color (pictures dont show this) and it appears to be hollow or possibly the marrow has fallen out but the inside looks quite smooth.

This was found on an anthill in the Hell Creek Formation, SD. A few years ago, a paleontologist at the South Dakota School of Mines looked at it and thought it could be avian. Can anyone out there confirm this? If so, any ideas as to species? Thanks for looking!

Here are six bird bones (I assume I am correct) from the Pleistocene of North Florida, USA. There are several different species included in this collection which I have no expertise in identifying(a complete amateur). Please anyone?

Hello TFF, I recently was able to glue this specimen together after its discovery this past fall. I need help with identification. It was found in the Niobrara in Logan Co, Kansas. After asking a tooth expert, he hypothesized that it is a Hesperornis. I've done a little research myself and I am not convinced of his conclusion. Of the Hesperornis pictures I've seen online, it appears that the top jaw lacks teeth at this part of the jaw, whereas my specimen is full of teeth. Additionally, there are two rows of distinctly different teeth on both the lower and upper jaw. One set is larger, more spaced teeth approximately 3mm apart and up to 4mm wide at the base. The larger teeth have all broken slightly and look like little volcanoes protruding from the jaw. The second row of teeth in the same jaw contains much finer and closely spaced teeth - about 0.5mm apart, 1-1.5mm wide, and about 2-3mm long. The two rows of teeth are slightly angled from each other - about 20 degrees or so. Any suggestions? I got a second opinion: Cimolichthyes...? What do you all think? Thanks for your help!

I processed some matrix today and found this small claw so I am interested to see what others think it is. The claw was found in the marine matrix from the Toolebuc formation that is a marine deposit that dates to the albian period in the cretaceous, about 100 million years ago of Australia it is found around Richmond in central Queensland. The scale in the photos is in half millimetres. the tip of the claw is broken of and what remains is about 5.5 mm long and about 1.2 mm wide. As the specimen is a claw I have eliminated the usual suspects of fish and marine reptiles so I am leaning more to the fly in type of suspect with bird and pterosaur the main contenders. I assume that due to the narrow width of this specimen the claws function is more to slice rather than to grip or scratch. Thanks in advance for looking and I hope some feed back. Comparative photos would be nice especially those of a better quality than I take. Mike D'Arcy
