I am fascinated by this taco-like concretion. Is its contents forever bound to the pyrite, left to me only speculation as to what it might be? Or can the matrix be removed to reveal what it contains?

Not sure if this is the correct venue.but I am interested as to what this could be. Central TX. Among landscape rocks first I thought it was petrified wood -
Discovered an intriguing tooth in an Austin, TX creek. Unsure if it's from a bison, cow, or horse. Any insights appreciated!

I found this tooth, and a bunch of other shark, fish, and ptychodus teeth in a creek in central Austin, Texas. I'm still trying to assess the age of the rock and better understand the geology of the area. I noticed a glint in the matrix while at home and gently wiggled it free. It really stood out as different. It's very curved, has a tiny cusp, and a line at the base. I'm still learning so I'm hoping to identify this tooth. Any ideas? Thank you in advance!

I found this rock in Austin, TX in Waller Creek next to an exposed outcrop of the Maastrichtian (Late Cretaceous) Austin Chalk. I’m wondering if it’s a mosasaur vertebra or humerus? Several mosasaurs have been found in creeks nearby, and the wavy pattern in the rock reminds me of fossilized bone. I’ve included three photos of the rock that I found in Austin, and a photo from Otero et al. (2016) of a Maastrichtian mosasaur right humerus (scale bar = 50 mm) that looks similar.

Found this strange fossil in a creek in Austin Texas. It’s been sitting around for a while, I’ve tried to look it up but I have had no luck. Im hoping someone more knowledgeable can help me out. The photo of the second fossil is included because of the strange engraving on it. It appears to be almost a swirl but I have no idea what might have caused it.

New Member/Fossil Hunter. Looking to ID some NSR and Austin Fossils/Artifacts!
Mikrogeophagus posted a topic in Fossil ID
Hi everyone! I'm a newer member to the fossil hunting community. I first started as a little kid, but have only really gotten into it over the pandemic as a hobby. I've done some hunting up around Dallas where I'm originally from, visiting famous spots like NSR and POC. For college, I'm currently living in Austin and have checked out a few nearby spots. These past few months I've been frequenting a local creek that runs through the Ozan layer and have been finding some cool fossils/artifacts. The items I am showing you today are collected from two places. The first assortment (lots 1 and 2) are from the NSR and contain Cretaceous/Pleistocene fossils. The second group (lots 3 and 4) was collected in Austin and contains Cretaceous fossils as well as some artifacts. For some objects, I am fairly certain of their identity, but for others I have no clue. Some fossils/artifacts have additional closeup shots for greater detail. Any comments or tidbits of wisdom concerning their identities or fossils in general would be greatly appreciated! Lot 1: NSR fossils I am fairly certain of 1A: Vertebra I believe to come from a mosasaur. 1B: My favorite piece from the NSR: A mosasaur tooth with a sizeable chunk of seems to be bone/root(?). It's a bit weathered, but there's still enough to get the imagination running! 1D: A nice little red bivalve from the red layer. 1E: A fragment of Pleistocene tooth I would love to know more about! From looking at the folds on it and doing some researching, I feel that it could be from a horse. 1G: The nicest piece of baculite I found that day. 1H: I'm not sure if this is a piece of coprolite or just a random cluster of two fossils. There is an identifiable baculite fragment and gastropod. Moving on to the second lot from the NSR, these are the things that I have very little notion concerning the identity of: 2A: Could just be an oddly shaped piece of sandstone (as it has that texture), but it does make me think of a scute. I would love to hear what y'all think! 2B: I truly have no idea what I am looking at. It feels like a fossilized "something", but that is all could really say. Here are some closer pics: 2C: Petrified wood? 2D: Very strange texture. My initial thoughts were some type of bone or petrified wood. 2E: Rock with fossilized bits of something that is difficult to identify. Maybe fish parts? 2F: A piece of cylindrical bone I believe. 2G: Piece of turtle? 2H: No clue. 2I: Petrified wood? Lot 3: Fossils from Austin Creek that cuts through Ozan layer 3A: Fairly certain this is an ammonite valve. Found quite a few in this creek for some reason. They never want to be whole. 3B: Good size vertebra likely from a mosasaur 3C: Really don't know what this is. My best guess is some really weathered down ammonite. It has symmetry and an overall spiral shape. It kind of reminds me of a curled up shrimp. Would love to know more about it! Here are some closeups: 3D: Nice little heart urchin. 3E: Nice urchin. I had only ever found heart urchins until this one, so it was an exciting find. 3F: Gastropod. 3G: Have yet to find a complete shark tooth from this spot, but here is a fragment. Might not be enough to secure an ID, but it's worth a try. 3H: Strange little fossil. Seems like some bryozoans grew on it at one point. When I look at it I get thoughts of echinoids and crinoids. Would be interested in hearing y'alls thoughts. Lot 4: Artifacts from the Austin creek (I know this isn't an arrowhead forum, but I figure there's a lot of overlap in hobbyists so there could be some insights): 4A: I believe this is a part of a larger tool like 4B. Not sure if these are knives, scrapers, or something else. 4B: Knife, scraper, or something else? 4C: My favorite artifact. Super pretty and thin. My guess is an atlatl dart point? 4E: another point, though not as visually appealing as 4D. The base looks a lot different too. Could this be an atlatl point? 4H: The base of some point. Would love to know more about the names or dates of any of these! If anyone would like more closeups of a specific item, feel free to let me know! -

Hey everyone! First post here. Found this in Austin TX on the bank of Walnut Creek. Thanks for the help!

What is this thing? It is completely shiny and pearlescent inside as if it was just alive. This is from a creek in Austin TX. Also, any idea what the other small bits are?

This was found in a Travis County TX creek. It's 9cm long and 9.5cm wide. I find mosasaur vertebrae from time to time, but rarely this massive, and never exhibiting biconvexity. Is it indeed mosasaur? Fused intercentrum? Time to turn to TFF for help on this one. Thanks in advance.

Can anyone help me identify these. They are coming out of several cliffsides on my property. At first glance they look like bones but they crumble and break easily and appear to have a smooth inside. Surround by seashells and i have found these shark teeth in the mix. This is in south austin close to onion creek, not too far from pilots knob volcano.
