jnoun11 Posted June 16, 2020 Share Posted June 16, 2020 hi guys i need your help for identification i have this strange tooth , look like tooth of sperm whale , eocen perhaps ypresian or lutetian. 1 Link to post Share on other sites
Fossildude19 Posted June 16, 2020 Share Posted June 16, 2020 Looks more like a piece of shell, to me. Oyster or bivalve. Seems too robust for fish. Link to post Share on other sites
jnoun11 Posted June 16, 2020 Author Share Posted June 16, 2020 hi fossildude its definitly a piece of bones, i look now on a direction of squids beak, coleoid or rhyncholites... Link to post Share on other sites
Al Dente Posted June 16, 2020 Share Posted June 16, 2020 A few more pictures of other angles might help. Is your scale millimeters? Link to post Share on other sites

jnoun11 Posted June 17, 2020 Author Share Posted June 17, 2020 hi guys thanks for the amelioration of the pictures. the scale is centimeter. whats about sperm whale tooth ? Link to post Share on other sites

A sperm whale tooth should have a pulp cavity on the bottom unless it has broken off. Then you should see concentric growth rings. What does the base of your fossil look like? This picture was found on a Google search. 2 Link to post Share on other sites
jnoun11 Posted June 17, 2020 Author Share Posted June 17, 2020 it s empty inside , i dont clean the inside because its my only way to know the real age, can be ypresian. Link to post Share on other sites
Al Dente Posted June 17, 2020 Share Posted June 17, 2020 If this is from one of the phosphate mines, it is too old to be a whale tooth. I believe the earliest whales are Lutetian and they have teeth that are much different than sperm whale teeth. 3 Link to post Share on other sites
jnoun11 Posted June 17, 2020 Author Share Posted June 17, 2020 i agree with you , i work on basilosaurus or papocetus and they are much more different shapes, but...it can be a lutetian spot in phosphates, or the origin of sperm whale are more ancient than we thinking... the enamel structure of the crown is like physeteroids whales but they are lutetian . the lutetian exist in moroccan phosphates horizon f of ben guerir https://books.google.co.ma/books?id=nw230cCn2EoC&pg=PA305&lpg=PA305&dq=lutetian+phosphates+morocco+bed+0&source=bl&ots=cFAhF3t5ZQ&sig=ACfU3U3sezkLuLXajl6OJ-aEJJ7QhhUwTg&hl=fr&sa=X&ved=2ahUKEwixsYTI4YjqAhUytHEKHX80CH8Q6AEwAHoECAoQAQ#v=onepage&q=lutetian phosphates morocco bed 0&f=false https://pdfs.semanticscholar.org/5aab/bd77ea9b8e64381bfd546b2cbf2c8bba6b79.pdf i m open for all identification or ideas. thanks for the help.

jnoun11 Posted June 18, 2020 Author Share Posted June 18, 2020 hi guys no clue ? or idea for this tooth? Link to post Share on other sites
jnoun11 Posted June 19, 2020 Author Share Posted June 19, 2020 somebody tell me that can be a sclerorhynchid rostral tooth, but the size is hudge if so... i keep going to wait more ideas for identifying this tooth... Link to post Share on other sites
Fossildude19 Posted June 19, 2020 Share Posted June 19, 2020 What about the possibility of it being a Rudist? @FranzBernhard @abyssunder Link to post Share on other sites

jnoun11 Posted June 19, 2020 Author Share Posted June 19, 2020 i dont think it s a rudiste the composition of rudistes are homogenous here this "thing" its heterogenous , somebody said too me it can be a pristis tooth, but the size and the curvature make me doubt about this proposition... i keep seeking.. thanks for the help 1 Link to post Share on other sites
abyssunder Posted June 19, 2020 Share Posted June 19, 2020 9 hours ago, Fossildude19 said: What about the possibility of it being a Rudist? @FranzBernhard @abyssunder The geological age and location is not proper for rudist. They dissapeared forever at the end of Cretaceous. Also it is very thin for a rudist and have a very nice pointed end. According to the dimensions, can't be an upper valve, just a lower valve, but considering that rudist were fixed with their lower valves to a hard substrate, there might be a root-like tiny attachment mark/scar or similar at the pointed end, not vissible in O.P.-s specimen. There might be another possibility, for an internal mold of a rudist. In this case the tip will be nicely preserved also other longitudinal/transversal striations. I don't think we are dealing with a rudist or internal mold of one, in my opinion. 5 Link to post Share on other sites
jnoun11 Posted June 23, 2020 Author Share Posted June 23, 2020 hi so , after further investigations: it s maestrichian, so,the last supposition: its probably the biggest and weirdest pristis ever found in a world. Link to post Share on other sites
jnoun11 Posted July 14, 2020 Author Share Posted July 14, 2020 hi i find more material in phosphate , too me look teeth, and i now eliminate pristis . so its big , its maestrichian, its phosphate , exist a canal inside, they are left and right, if somebody can ask friend or scientist for trying to solving this mystery , welcome. 1 Link to post Share on other sites
Al Dente Posted July 14, 2020 Share Posted July 14, 2020 If the two pieces go together, it would look similar to Titanosarcolites. Link to post Share on other sites
jnoun11 Posted July 14, 2020 Author Share Posted July 14, 2020 hi aldente its bones , and they didnt go together. interesting idea the rudist , but in phosphate deposit we didnt have invertebrates, or only internal molds. thanks for the help. Link to post Share on other sites
JohnJ Posted July 14, 2020 Share Posted July 14, 2020 @Boesse Maybe Bobby has seen something like it. Link to post Share on other sites
Boesse Posted July 14, 2020 Share Posted July 14, 2020 I don't recognize these at all, and suggest that they are either mollusks or perhaps fish teeth. If the latter, they would have to be from a pretty weird fish, but the flaky texture is fish-like - also possible with mollusks, though. Link to post Share on other sites
JohnJ Posted July 14, 2020 Share Posted July 14, 2020 Thanks, Bobby. @Carl or his associates may have a lead. 1 Link to post Share on other sites
ceklund Posted July 15, 2020 Share Posted July 15, 2020 Could it be a horn core? If it is Eocene, there were probably some horned beasts then. Link to post Share on other sites
