TxHillRock6423 Posted January 22, 2022 Share Posted January 22, 2022 Hello all, looking for a little help with the identification on a few items my kids and I have picked up at our ranch in the Texas Hill Country, located in Kimble County. We have just started down our adventure fossil hunting and to this forum. Please be patient with me. Thank you all for the help and I’m looking forward to learning and growing with this community.

ClearLake Posted January 22, 2022 Share Posted January 22, 2022 The top group is a bunch of oysters, something like Lopha. Most of the rest look like concretions, chunks of chert or other rocks. Nothing jumps out at me as being bone. 1 1 Link to comment Share on other sites More sharing options...

JamieLynn Posted January 22, 2022 Share Posted January 22, 2022 All of the oysters are Ceratostreon, a common oyster found in the Texas Cretaceous. As Clearlake said, everything else is limestone and chert nodules with the exception of THESE: A weird bivalve called a rudist. They are one of my favorite things to find! 3 1 www.fossil-quest.com Link to comment Share on other sites More sharing options...

Lone Hunter Posted January 22, 2022 Share Posted January 22, 2022 Looks like you got some oysters, some chert, maybe flint, and some neat concretions, others I don't recognize. Someone more knowledgeable will give more specifics, it would be helpful for reference if you could number them, you can still edit. 1 Link to comment Share on other sites More sharing options...

AJinTexas Posted January 22, 2022 Share Posted January 22, 2022 The pieces in the bottom left of 1st photo are gastropod segments. I'm not sure how accurate all the names are, but I have been using the fossil quest website for ideas of what to look for out here. You have a few different species in that photo (looking at the ridges), but I am too green to name any with confidence. Keep a look out for some clam steinkerns (casts) in this area! There are loads of them. Ledges / cliffs and erosion prone areas (especially where the limestone periodically crumbles away) are great places to find nice specimens. There are plenty just sitting on the ground too (typically more worn); so if you see a clam shaped rock, pick it up and check it out! Looking at your photos again, the large rock 2nd from the right, in your last group of photos, looks like it might be a large clam cast with a chunk broken off (or not fully formed)... But the larger they are, typically the more worn and harder to tell if it is one or not. It could just be a coincidentally shaped rock, but I'd be interested to see the reverse side of that one. Happy hunting! 1 Link to comment Share on other sites More sharing options...

AJinTexas Posted January 22, 2022 Share Posted January 22, 2022 It certainly looks like one, and coming out of the hill country, I would say it is a clam cast. But I am certainly not an expert, so maybe someone with more experience can weigh in. Nice one! 1 Link to comment Share on other sites More sharing options...
