Auspex Posted January 11, 2015 Share Posted January 11, 2015 Do we assume from your labeling that you propose these to be fossil brains?

verydeadthings Posted January 12, 2015 Share Posted January 12, 2015 Sorry, doesn't look like a brain or fossil to me. Maaaybe there's an external mold of a crinoid stem fragment in your last picture, labeled "main vein of cerebellum." The picture is too blurry to be sure about that. Pour some acid or vinegar on it and see if it fizzes, that will at least tell you whether your rock is limestone. When you're trying to identify something, you start with the most plausible options, and work your way down to the more implausible options. Fossil skulls are rare, fossil endocranial casts are rarer still, and fossilized brain tissue is extremely rare. See Pradel et al. (2009) for an example of fossilized brain tissue (http://www.pnas.org/content/106/13/5224.full). Do some research, find out what kind of fossils are common in your area and where to find them, and come back to us with some more stuff to identify Link to comment Share on other sites More sharing options...
howard_l Posted January 12, 2015 Share Posted January 12, 2015 It looks like a chert replaced limestone and it looks very much like a crinoid stem cast in the last photo. If you can determine where it came from and maybe its age you can rule out curtain things.

Please do get out and find more, but don't take Hunter S. Thompson with you next time. Cole~ Knowledge has three degrees-opinion, science, illumination. The means or instrument of the first is sense; of the second, dialectic; of the third, intuition.
