sixgill pete Posted August 26, 2016 Share Posted August 26, 2016 I recently received a box of micro matrix from a forum member Otodusobliquus. It was a packed full medium sized usps box about 2 1/2 gallons. After re-sifting through a 1/4 inch mesh to remove the few larger pieces and thoroughly cleaning I ended up with about a gallon and a half of searchable matrix. When searching micro matrix making sure the matrix is complete and thoroughly clean is very important; otherwise you can and probably will miss many of the smaller teeth. This particular matrix I washed 4 times before I was satisfied that it was clean enough for searching. While cleaning I used a small sifter with .75 millimeter mesh. I have searched through about a quart of the matrix to this point and have been very satisfied with the variety, condition and the amount of finds. I thought I would share some of them with you all. If I have any of these ID's incorrect please correct me (especially you Marco) First a really beautiful Odontaspis winkleri: A few different Triakids; if you hold the cursor over the picture my ID will appear.

MarcoSr Posted August 26, 2016 Share Posted August 26, 2016 Don I'm really interested in seeing the gar scales. In forty years of collecting the Aquia Formation I've only found two fossil gar scales. My son Mel has also only found two fossil gar scales. Gar are currently present in pretty good numbers in the Potomac River. I just brought home a skull, upper jaw and a good number of scales from one I found on the beach. The modern scales are white to cream colored.

I don't think any of the specimens in both replies are Otoliths. Below are two examples of Otoliths from the Aquia Formation. Fish Otolith1 4mm.jpgFish Otolith2 3mm.jpg I do not believe the one specimen is Burnhamia. It looks much more like a lateral Myliobatis tooth. Burnhamia are pretty uncommon in the Aquia. Marco Sr. Thanks Marco. I just realized I did not give a size on any of these. The imitation otoliths range from 6 to 9 MM. I am still working on learning to ID these Paleocene goodies. I was using your previous posts, elasmo.com and your website. So your help is much appreciated. I am relabeling the ray tooth as Myliobatis sp. lateral.

The second tooth looks like a Foumtizia. See the picture below of a Foumtizia from the Aquia Formation. Foumtizia abdouni 2mm.jpg Marco Sr. Marco the first tooth is right at 4mm. The second tooth is rather worn but is the right size for Foumtizia. I had the bag labeled as udet. catshark. So I think I will relabel it. Thanks.
