Fossil_finder_ Posted March 22, 2021 Share Posted March 22, 2021 I was hunting a site on the Potomac looking for some Eocene and Miocene fossils yesterday. When I got to the site I found this gorgeous snake vertebrae about 15 minutes into my trip, so I knew it was going to be a good day. After that it was slow collecting for the next few hours, I was only picking up a tooth every once in a while despite the incredible conditions. But then, 10 minutes before I was about to leave I stumbled upon my best chubutensis yet at about 2 3/4 in. (or 7 cm) rolling around in the surf. One that I have been dreaming about ever since a starting collecting two years ago. A total trip maker! I hope you enjoy the pics! 4 8 Link to comment Share on other sites More sharing options...
digit Posted March 22, 2021 Share Posted March 22, 2021 It's always gratifying to have a fossil hunting trip capped off with a real trip-maker prize. Persistence pays off (unfortunately though, not every single time). You'll remember finding this tooth for years. Cheers. -Ken Link to comment Share on other sites More sharing options...

Plax Posted March 23, 2021 Share Posted March 23, 2021 almost looks like an angustidens. Any chance there's some old church lag in the exposures? Link to comment Share on other sites More sharing options...

This was in Maryland and, coincidentally, I asked a similar question last week in another forum about a tooth I found upriver. According to @WhodamanHD, there are no known old church fossil exposures in MD where an angy could be found, although it's not beyond the realm of possibility. @MarcoSr 2 Link to comment Share on other sites More sharing options...
Plax Posted March 23, 2021 Share Posted March 23, 2021 The lag between the Miocene and Eocene may not be the Old Church Formation but may include Old Church resistant clasts like shark teeth. Link to comment Share on other sites More sharing options...

The place he’s likely hunting has the lowermost bounds of the Calvert FM, so this is an early chub probably. Old Church angustidens are less developed, I don’t think the formation has been accurately dated but I suspect it’s older than the SC oligocene. Thus, I don’t believe this is from it. We don’t have a good site spanning the transition between Chubs and angys, so we don’t often see ones like this. It’s a nice find, as is the Palaeophis grandis! 2 “...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...

It’s a nice find, as is the Palaeophis grandis! Why, thank you Mason And you are correct on your inference about the site I was hunting at. It does contain the Calvert formation which appears on top of the Nanjemoy Fm. (at least I think it's Nanjemoy) 1 Link to comment Share on other sites More sharing options...

Your hard work certainly has paid off and I hope you hang onto that tooth and keep it someplace in where you can see it frequently. As you continue in your fossil hunting journey, those trophy teeth are a tangible reminder of awesome days in the field in good company and of the thrill of a successful fossil hunt. BTW, I was down that way on Saturday and we didn't find much on the some of the beaches. You must have found them all! Congrats! 1 Link to comment Share on other sites More sharing options...

According to @WhodamanHD, there are no known old church fossil exposures in MD where an angy could be found, although it's not beyond the realm of possibility. @MarcoSr The features of your tooth look like an O. chubutensis. Where you were collecting, I've found O. obliquus, transitionals, and O. auriculatus from the Nanjemoy Formation and the lag layer between the Nanjemoy Formation and zone 3 of the Calvert Formation. I've found mostly O. chubutensis and only a few O. megalodons from the Calvert Formation. However, I have found a couple of teeth that look more O. Angustidens and other possible Oligocene shark teeth from the lag layer during the 45 years that I've collected the area. Although I can't say with certainty, I suspect that there might be some Oligocene specimens in the lag layer in very localized pockets along the lag layer. Edit: Below is a picture of a display with teeth from the area. The two teeth circled in red are the ones I was discussing above. The crowns are rather wide to be O. auriculatus and the serrations don't seem as uniform as O. chubutensis. The colors of these teeth are in line with colors from the lag layer.
