DeepTimeIsotopes Posted January 13, 2019 Share Posted January 13, 2019 I’m wondering what the age of the Otodus teeth are in Morocco. Does anybody have any papers on the teeth there? Also, does anybody know how many genera there are there? Thanks 3 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic........... Paleo......Meso....Ceno..

SailingAlongToo Posted January 13, 2019 Share Posted January 13, 2019 Otodus obliquus are Paleocene into Eocene. 4 Don't know much about history Don't know much biology Don't know much about science books.........

Here’s a good website that lists the sharks and rays from the phosphate mines. There are photos of most of the species. http://users.telenet.be/sharkteethcollection/ray list totaal/Ray list totaal.htm 6 Link to comment Share on other sites More sharing options...

siteseer Posted February 6, 2019 Share Posted February 6, 2019 As illustrated in the chart, I have always heard that Otodus dates back to the Late Paleocene in Morocco though it's more common in the Early Eocene. It might go back to the Early Paleocene elsewhere - a site in Russia and maybe even New Jersey. There is one article I know of: MacFadden, B.J., J. Labs-Hochstein,, I. Quitmyer, and D.S. Jones. 2004. Incremental growth and diagenesis of skeletal parts of the lamnoid shark Otodus obliquus from the early Eocene (Ypres) of Morocco. Palaeogeography, Palaeoclimatology, Palaeoecology 206: 179- 192.
