val horn Posted August 27, 2020 Share Posted August 27, 2020 Found this in a marine late cretaceous formation in Maryland. Two bones that were immediately associated with each other. I thought the flat bone was turtle when I saw it, but this other bone was just underneath it. Now I really dont know what I am looking at. help?

Anomotodon Posted August 28, 2020 Share Posted August 28, 2020 Interesting! I believe the long bone is a distal femur end, could be dinosaurian, here is a hadrosaur femur for comparison. More pictures from anatomical positions and precise formation info are necessary to verify though. The Tooth Fairy Link to comment Share on other sites More sharing options...
Rockwood Posted August 28, 2020 Share Posted August 28, 2020 Bone ? Is the texture still mostly hidden ? Link to comment Share on other sites More sharing options...
val horn Posted August 28, 2020 Author Share Posted August 28, 2020 It is severn formation marine near shore appr 80 myo. This is bone, most bone at this site gets a hard irregular coating . Maybe one could remove it with sandpaper maybe not without damaging the existing surface. enclosed photos of shark teeth and mosasour tooth to show the typical coating. also I have tried to get more classic anatomical photos. I would be very excited to have a dino bone. Very occasionally some dino material has washed into this formation-- particularly in the similar marls in New Jersey. 3 Link to comment Share on other sites More sharing options...
Anomotodon Posted August 28, 2020 Share Posted August 28, 2020 Thanks for the pics! Definitely terrestrial material, I still think it's a Hadrosauroid distal femur. 4th trochanter position and the foramen size compares well to hadrosaurs and completely different from crocodiles and turtles. 1 The Tooth Fairy Link to comment Share on other sites More sharing options...
val horn Posted August 28, 2020 Author Share Posted August 28, 2020 thank you for your help. Hadrosauroid, wow. That makes this a bucket list find for me. Just noticed that you are from Kyiy, My grandmother came from a small town near Kyiv. Sometimes it is a small world. Link to comment Share on other sites More sharing options...
