rdrass Posted November 11, 2011 Share Posted November 11, 2011 My father found this tooth in a stream bed in Davis Co. Iowa. Could anyone tell me any information about it, and if there is any reason to doubt that it originated here. Link to comment Share on other sites More sharing options...
Paleoc Posted November 11, 2011 Share Posted November 11, 2011 Probably Cretalamna and while I have not heard of any teeth from Iowa it is certainly possible. Link to comment Share on other sites More sharing options...
Auspex Posted November 11, 2011 Share Posted November 11, 2011 An extinct Mackeral Shark from the Cretaceous; certainly a rare find in Iowa!

MikeDOTB Posted November 11, 2011 Share Posted November 11, 2011 Yep, it could be possible, the tooth does look reworked as well. Do you know anythin about the age of exposures in the area? DO, or do not. There is no try. Link to comment Share on other sites More sharing options...
MikeDOTB Posted November 11, 2011 Share Posted November 11, 2011 Yep, just a quick google search and there seems to be pleny of information about Iowa and shark teeth. Most are found in "glacial tills and associated gravel deposits". Check this out: http://www.igsb.uiowa.edu/Browse/dinosaurs/age_of_dinosaurs_in_iowa.htm DO, or do not. There is no try.

siteseer Posted November 12, 2011 Share Posted November 12, 2011 I think there is an article on Late Cretaceous marine vertebrates of Iowa but it doesn't appear I have a copy. Fossilselachian might know the article. I know Mississippian-age teeth used to be found in the Burlington Limestone around Augusta. Link to comment Share on other sites More sharing options...

Sorry Jess (and others) but I don't have a copy of the referenced article. Link to comment Share on other sites More sharing options...
