There has been much debate about the identity of this strange item on the forum. I finally solved the mystery thanks to the (click next) Calvert Marine Museum web site . These are a reasonably common find on the beach near Matoaka Cabins. They vary in size and shape, owing to the different species and ages of the sharks that produced them as much as the teeth shed by the same sharks. What they all seem to have in common is the black, polished surface, the generally oval shape (which can vary in proportions), and the appearance of an outer coating that splits on one side.

Found on the beach near Matoaka Cabins. This is the largest one I have found to date.

This was excavated from a block of matrix collected from submerged landslide material in the Chesapeake Bay. The common name of the shell is pronounced "gooey-duck." The height listed is the diameter of the opening between valves on the posterior side, where the siphon extended.

Chesapectin nefrens is an index fossil for the Drum Cliff Member of the Choptank Formation. This example is particularly nice because the interior is almost completely layered in pearl.

I erroneously identified this earlier as the similar Turritella plebia, until looking at one more reference! Mariacolpus octonaria is an index fossil for the Drum Cliff Member of the Choptank Formation. Donated to the Delaware Museum of Natural History

This specimen and dozens like it were collected from matrix material deposited in the waters of the Chesapeake Bay by a landslide. It is one of only a few species that consistently survived intact in the matrix samples I collected. Most specimens were single, unbroken valves, but several had both valves together and intact. A. tisphila is considered the most abundant find in the Choptank Formation. It is an index fossil for the Drum Cliff Member. This specimen was donated to the Delaware Museum of Natural History.

Found at the Beach near Matoaka Cabins, E. marylandica is an index fossil of the Boston Cliffs Member of the Choptank Formation. The genus for this animal bounces back and forth between Marvacrassatella and Eucrassatella. WoRMS lists it as being re-assigned to the Eucrassatella genus. As of this update (November 8, 2017), the Eucrassatella genus has been restricted only to Indopacific species, so the genus was reverted to Marvacrassatella. This specimen was donated to the Delaware Museum of Natural History.

Hello all! I have looked all over and I can not ID this. Maybe it's nothing but the texture is really cool. It was found in the Chesapeake Bay in Calvert County Maryland. Would love to hear your thoughts. Thank you! Here is the back

So... I was on the Chesapeake Bay a few weeks ago and I found this little oddball. At first I thought it was plant based, because it sort of looks like a plant bud. But when I picked it up, it is definitely a tooth. You can't tell from the pictures but the top of the black root is hollow inside. I actually suspect that this is not a fossil and that it is a current tooth, partly because of the vibrant colors. I figured I would ask the experts. :-) any chance of this being Miocene?

Hi. I keep learning new things all of the time. One of the things I learned last year is that crocodile teeth are hollow inside. I have a few from over the years so I checked them out. Yep, they were all hollow.. except for one. So I am guessing this isn't really a crocodile tooth. I will post it for the experts to comment on. It is about the size of a 50 cent piece for reference. Also, I can't remember exactly where I found this one. It was either a day when I was allowed into Scientist Cliffs, or it might have been a trip I paid for to Stratford Hall. I believe it was Scientist Cliffs.

I thought I would ask the experts for a little validation. :-) I found this nubby little tooth, about the size of a quarter, on the Chesapeake Bay. It isn't apparent from the picture but it is serrated. I will try to get a better photo tonight in better light.. I know the photo is bad. ( It is next to a couple of seven gills and a tip of a Meg that certainly would have been nice to have found complete.. ) I'm thinking a very tiny Meg tooth, because it is certainly not a hemipristis. I just didn't think Meg's could be that small. Thanks for any help..

Work and life have been busy, so I haven't had a chance to post this before. About six weeks ago I took a day off from work...It was going to be stupid warm that day for November (I think it got up to 80 that day)...and decided I wanted to go looking for teeth. I couldn't go to my normal hunting spot that day (closed)...so decided to contact a friend of my wife and myself who lives in a community that has access to a beach on the bay, and off I went. So I parked at her house, walked the couple hundred yards down the hill to the beach...and then walked a couple of miles along the water before I got to any areas with any exposed clay or otherwise had any potential. Suddenly, I saw it...I couldn't believe it...walked right up to it...it was just laying there fully exposed saying 'pick me up'. I took a very short video as I came up on it: As you can see...the root is kind of chewed up...but otherwise...a pretty nice tooth. Good serrations...tip in good shape too. About 3 1/4 inches. I've found one or two a bit larger over the years, but none had enamel that was in such good condition as this one. It was the first tooth I found that day...and frankly, I should have just left at that point...despite another couple of miles of walking on the beach, I found nothing else of significance. Oh well, I'm not complaining.

Hey everyone, This is my first post, although I have been looking for and collecting fossils in the York River and Hampton areas of Southeastern VA for sometime now. But I found a fossil the other day that gave me the jumpstart I needed to join up here! So on the beach in Hampton the other day after the remains of tropical storm Julia rolled through, and I found something that puzzled me greatly. It appears to be a horn coral..but there are problems with that as a diagnosis. The fossil layers in the area are far too young for a horn coral. The layers present nearby are the Yorktown, Eastover, and maybe some of the St Marys and Calvert since the edge of the Salisbury embayment borders the Hampton beaches. So layers no more than approx 15 million years. The fossil is also flattened out some. So does anyone have any ideas? A medusa/jellyfishy thing of some kind? A horn coral that found it's way from the mountains all the way to the bay? Thanks all

It was my every-other-Friday off today, so I decided to go down to my favorite spot on the Chesapeake today...figured I'd try to get some hunting in before the early afternoon rains that were expected moved in. When I hit the beach, I immediately saw a 1 1/2 inch mako tooth sitting there waiting for me....a good sign? Debris was decent but not great. I made the usual trek...I usually cover about a 1/2 -3/4 mile of beach...turned around and headed back toward where I started. On my way back I reached the area of the beach I usually prefer to 'work'....about 100-200 yard worth...back and forth....checking at various times the beach....the debris line...and spending a fair amount of time in the water looking for interesting things on the bottom among the rocks and oyster shells...the water was clear today...so I could see the bottom well in water a foot and a half deep. At some point, some fellow hunters I know showed up...they joked that on their way down, they hadn't found anything...a problem they blamed on me. Haha. I showed them a few 1 1/2 inch makos I had found...some nice hemis...but acknowledged that I hadn't found anything noteworthy. Within a minute or two of chatting...as they scoured the beach/debris line and me about 15 feet out from shore looking over the bottom...I spotted something that, color-wise, looked like another slightly green algae/slime-covered oyster shell...but something about it's shape caught my eye. As I scooped it up along with other shells and rocks, I saw enough of it to know what I had...I fished it out of my scoop...started to rub and wash the green off...and walked over to my friend and told him that he won't believe this.... It was a 2 3/4 inch megalodon...in pretty good shape for a tooth found in the water. Over the 3 or 4 years I've been doing this here, I've found a handful of megs...and even more half megs and assorted fraglodons. But this was the largest, nicest intact meg I've ever found. Quite a lot of wows and hoops and hollers out of my fellow hunters. One grabbed it and ran off...lol. Below are some pictures - one of it taken at the beach. There's a picture of the finds for the day...which included a few makos and a nice whale vert. No trip tomorrow....(boy it sure is nice living 15 minutes from the Chesapeake!)...going to the fossil, rock and mineral show at George Mason University in Northern Virginia tomorrow....along with some other shopping....Christmas is coming up fast. And no trip Sunday...it's going to be windy and only going to get up to 35! I'm not ready for that kind of cold yet. 2 1/2 inch mako a couple of weeks ago, and now this...Fall's looking good so far!
