ChurrO Posted May 22 Share Posted May 22 Hey, As a little recap to the last posts, a bit ago me and family were working on an excavation project for a house within Caldwell County in Central Texas and accidentally broke through the upper cretaceous layer (namely the Navarro group) and found a bunch of fossils. I've been trying to ID some of the stuff but I ran into a wall on some finds so I'm hoping to get some help. 1. This looked really interesting to me because of the shape. Almost looks like a tooth of sorts but it could be bone as well. 2. I know its a bone, but i was wondering if its possible to ID from what animal it came from. 3. This had an odd shape to it, but I couldn't figure out what it was. From here on out, these are some smaller fossils. Sorry if it's a bit blurry, I had to get a microscope to get a decent picture. All of them are withing the range from 1 - 5 mm in length. 1a. maybe fish tooth? 2a. I'm pretty sure its fish teeth, but I has hoping to get the species. 3a. I'm thinking denticles? 4. No idea. Maybe another type of fish tooth? 5. I think it's a shark tooth, namely squalicorax sp, but I'm not sure. I know this was a bit lengthy but I would appreciate all the help I can get. Thanks for the help! 2 Link to comment Share on other sites More sharing options...
Chalkdude Posted May 22 Share Posted May 22 I agree with squalicorax on number 5 but not sure of the exact species. 1 1 Link to comment Share on other sites More sharing options...
Mikrogeophagus Posted May 23 Share Posted May 23 1 and 4 look like bases of Ischyrhiza mira rostral teeth and 1a could be the tip, but it's hard to say. Need more angles. 2 looks bony to me rather than toothy (spongey texture instead of layered enamel). I agree with Squalicorax for 5. 3a look like Ischyrhiza denticles of various species (avonicola, monasterica, etc.) though they are a bit enigmatic. It is tough to say whether they are actually from a different species than I. mira or just a different part of the body/rostrum. Here is an I. mira rostral for reference. Note there can be variance in morphologies. Differences in yours could be due to weathering/reworking (they do look pretty reworked) 9 hours ago, ChurrO said: Here is a website that covers sharks from the Navarro Group (Kemp Clay) in TX: http://www.elasmo.com/frameMe.html?file=genera/cretaceous/ptychotrygon.html&menu=bin/menu_genera-alt.html 3 Link to comment Share on other sites More sharing options...
automech Posted May 23 Share Posted May 23 Nice "accident" to happen! Great finds! 1 Link to comment Share on other sites More sharing options...
Anomotodon Posted May 23 Share Posted May 23 Cool finds! I think #2 is also an Ischyrhiza rostral tooth, just heavily eroded (root + base of the crown). #4 may be partial reptile teeth, possibly mosasaur, or some teleost fish. 1 The Tooth Fairy Link to comment Share on other sites More sharing options...
