Shellseeker Posted July 4, 2016 Share Posted July 4, 2016 Some of my friends, who are Florida in_season fossil hunters, go home in the summer and find places there to hunt (the lucky devils). In this case they were hunting "near the Bear Paw shale formation in Montana. Could you tell me what they are? My daughter and I tried to look them up, but couldn't find much. Are they brachiopods? Cephalopods? you're the man to ask! Some are agate. Some are crystal. Beautiful! Thanks and see you later." I keep trying to suggest a TFF membership, but to no avail!!! Here are a few photos: I will go back for sizes if necessary but these look to be a couple of inches square..Kind of pretty with the crystalline snowflake patterns.

ynot Posted July 4, 2016 Share Posted July 4, 2016 Baculites and ammonites. Nice -- loving the crystallization of them. Tony Link to comment Share on other sites More sharing options...

fossilized6s Posted July 4, 2016 Share Posted July 4, 2016 yup, Baculites and a Ammo bit. Looks like calcite crystals. Very neat! ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Guguita2104 Posted July 5, 2016 Share Posted July 5, 2016 Fantastic Ammos and Baculites (wich is also a heteromorph ammo)! Regards, Link to comment Share on other sites More sharing options...
Ridgehiker Posted July 5, 2016 Share Posted July 5, 2016 The suture patterns in most baculites species are quite distinct....as are the ones in your specimens. The specimens you have are 'Baculites compressus'. This species is used as a marker to date other fossils in the formation. Calcite crystals usually indicate transitional zones between marine and terrestrial. So not unusual to find dino material and calcified marine fossils in close approximation. When I find a lot of calcite, I look for Tyranossaurid teeth as they survive the erosion of softer bentonite layers and get deposited among the crystals. 2 Link to comment Share on other sites More sharing options...

Shellseeker Posted July 6, 2016 Author Share Posted July 6, 2016 Thanks to all. As always, I am impressed by the detailed knowledge and willingness to share exhibited by TFF expert membership.. Thanks I had a couple of more photos, not added in the original post. Here they are -- seems like a great place to hunt. Bear Paw -- I will have to remember that...

Miatria Posted July 7, 2016 Share Posted July 7, 2016 yes, those are the suture lines on ammonoids but I'm not sure what the last 2 photos are. Zookeeperfossils.com Link to comment Share on other sites More sharing options...
