pleecan Posted December 22, 2009 Share Posted December 22, 2009 Just a guess.... Reminds me of a pyritized horn coral from the Devonian.... what age is the rock strata? PL Link to comment Share on other sites More sharing options...
TourmalineGuy Posted December 22, 2009 Share Posted December 22, 2009 In addition to the strata age, where is it from? Link to comment Share on other sites More sharing options...
Nicholas Posted December 22, 2009 Share Posted December 22, 2009 Looks like coal to me, probably horn? We need some more info though. Link to comment Share on other sites More sharing options...
JohnJ Posted December 22, 2009 Share Posted December 22, 2009 The cryptic title suggests it is from Post Oak Creek, North Texas - Upper Cretaceous, overlain with Pleistocene gravels. Not very big, is it? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
kknight Posted December 22, 2009 Author Share Posted December 22, 2009 whoops, I left out the info about what POC stands for. Forgot not all of us are from Texas JohnJ is correct it is Post Oak Creek, North Texas - Upper Cretaceous, overlain with Pleistocene gravels. The thing is pretty small, the scale is in CM. I can't determine if it is from the Pleistocene gravel or the Cretaceous since it is all mixed into the creek gravel.

frozen_turkey Posted December 25, 2009 Share Posted December 25, 2009 I am trying to determine if this is just a nodule of some kind or part of a fossil. One end does have some sort of pattern to it, but I can’t tell if it is just the way the rock formed. I has to be a horn coral i have no clue what else it would be. We have horn coral coming out of our ears down here and they rang from 1/8 of an inch tall to 2 feet tall. -Frozen Link to comment Share on other sites More sharing options...
tracer Posted December 25, 2009 Share Posted December 25, 2009 it isn't a horn coral. some sort of iron-based nodule or burrow infill. Link to comment Share on other sites More sharing options...
