Andy Posted February 28, 2008 Share Posted February 28, 2008 I have a mako shark tooth and two coal-age fossils. The shark tooth is a mako, possibly from Aurora, NC. What I want to know is what kind of mako? The next two pics are from a fossil tree root found in a coal mine in Tennessee. What is it? And the last pic is fossil bark from a coal mine in Georgia. Do you know what species it could be? Calamites? Thanks- Link to comment Share on other sites More sharing options...
ebrocklds Posted February 28, 2008 Share Posted February 28, 2008 the first two pictures of plants are Stigmaria. they are the roots of the Lepidodendron tree, which is also the identification for the last picture that you have posted. they are most likely carboniferous in age.

jbstedman Posted February 28, 2008 Share Posted February 28, 2008 The tooth in the first picture does appear to be a Mako -- specifically Isurus hastalis. I assume the labial side is flat.

Northern Sharks Posted February 28, 2008 Share Posted February 28, 2008 The mako is Isurus hastalis There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted February 28, 2008 Share Posted February 28, 2008 The last picture does not look like any type of lepidodendron I've ever seen. I find a lot of this stuff in Bama, and lepidodendron always has bark that has diamond shaped/triangular shaped scales to it. It looks more like calamites to me, but what I find has 'ribs' that are much finer, not as large as what you have, but then again there are most likely several species of calamites that I have not seen. The others do indeed look like stigmaria or root. Very nice ones too. Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted February 28, 2008 Share Posted February 28, 2008 ^ I think it is a Sigillaria. Another type of Lycopsid. It could however be one of the inner barks of the Lepidodendron.. EDIT: Or one of the inner barks or Sigillaria. I'm not sure of Sig. barks, but I believe the Lepidodendron had 7 "layers" and innermost ones didn't exhibited the scars. Link to comment Share on other sites More sharing options...
Andy Posted February 28, 2008 Author Share Posted February 28, 2008 Looking at it, I think it sigillaria too. What do you think? Thanks- Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted February 29, 2008 Share Posted February 29, 2008 Yeh, sigillaria looks better to me than Lepidodenron. I thought the 'ribs' were too large for calamites. Link to comment Share on other sites More sharing options...
