neotriumvirate Posted March 4, 2014 Share Posted March 4, 2014 I found this in the river rock landscaping that borders my house near Detroit, MI. I have no experience with fossils. It looks to me like it could be a fossil, I was wondering if anyone could tell me what it is. Thanks, John L. Link to comment Share on other sites More sharing options...
ted coulianos Posted March 4, 2014 Share Posted March 4, 2014 looks like you have a very badly weathered & tumbled horn coral; the evenly spaced "lines" are the coral's septa. hope this helps. Link to comment Share on other sites More sharing options...
lissa318 Posted March 4, 2014 Share Posted March 4, 2014 http://www.thefossilforum.com/index.php?/topic/38608-carboniferous-cone/ The small round circle in the second pic looks an awful lot like a calamite node to me though? Check out the link above for pictures to compare. Link to comment Share on other sites More sharing options...
Auspex Posted March 4, 2014 Share Posted March 4, 2014 I think coral; the septa have weathered out, leaving deep, narrow grooves.

Kman100 Posted March 4, 2014 Share Posted March 4, 2014 Could the small round circle be a crinoid? -kevin Link to comment Share on other sites More sharing options...
Carl Posted March 5, 2014 Share Posted March 5, 2014 That, too, looks like a coral. Link to comment Share on other sites More sharing options...
Tethys Posted March 5, 2014 Share Posted March 5, 2014 Yes, its a horn coral. The round "flower" is a type of bryozoa. There is another one just to the lower right, but it is very eroded. I can't find it at the moment, but I have a picture of that exact species somewhere in my files. Link to comment Share on other sites More sharing options...
