Miocene_Mason Posted December 3, 2017 Share Posted December 3, 2017 Hello everyone, went to brownies beach last week, was crowded for the beach so finds were limited. Did find a few nice but common teeth and as always a good amount of chunkosaurusesr. Highlight was a chunk of jet. Anyway, I found this tiny tooth (5 millimeters slant height). Pictures taken with microscope. Miocene, Calvert FM (zone 4?), brownies beach. Any ideas? 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Troodon Posted December 3, 2017 Share Posted December 3, 2017 I like those small teeth since they are hard to find. When there was a fall on the cliffs and a fossil zone exposed I would bring a fine screen and go through that layer carefully. Link to comment Share on other sites More sharing options...

I don’t sift or screen because I don’t like carrying a sieve around, I just pick up what I see (I get close to the ground, wears on the back but worth it). There was a little cove formed in the cliffs with a ton of shell pieces that a looked in to find the galeocerdo. Thanks again for your help! 1 hour ago, Tidgy's Dad said: These are beautiful.

It’s hard to tell really what you have until you go home and get a good look at it. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

See the below link: EDIT this shows the differences of posterior teeth between the extant Carcharias taurus and Odontaspis ferox. Carcharias cuspidata is abundant in your time period. You can find Odontaspis ferox and reticulata also in your time period. http://naka.na.coocan.jp/JAWodondaspidae.html Marco Sr. 3 "Any day that you can fossil hunt is a great day."

This will be helpful for many other teeth I have as well! 4 hours ago, hauyn888 said: Hi Mason - great find, even if the tooth is small -congratulation Thanks! I like the little ones, which is good because when the beach has already been combed they are the only ones left. Biggest tooth that day was half a hemipristis at ablout an inch, and that was beyond the main beach. ——————————————————— there are hundreds of tiny teeth there, most I find I give away to kids or unlucky adults (if there’s no one else there I throw them up onto land because I hate the thought of the being destroyed by the waves) but this lemon I stuck in a log.

Packy Posted December 9, 2017 Share Posted December 9, 2017 You should try sifting and washing some sand from there and looking at it with the microscope, you may be surprised at how small they can be. I have a bunch from the carlise shale in North Dakota. Its awesome how small they can be. Packy Link to comment Share on other sites More sharing options...
