    NJ Paleocene ID Help

    This past weekend I had the chance to collect at an exposure of the Paleocene Vincentown Formation in New Jersey. The trip was a lot of fun and a number of really cool fossils were found. I have been able to identify most of my finds except for these two mystery fossils. I recognize the shark tooth as a sand tiger but I was hoping someone might know which sand tiger it is. I saw online that someone listed Carcharias samhammeri in the Vincentown but I am not an expert on shark teeth so I am not sure if that is what this tooth is. Any help is greatly appreciated! #1- bryozoan?
  2. I found what looks to me to be a coral fossil in a stream in Kent county Maryland and I would like some help identifying it. I tried to make my pictures as clear as possible but the fossil is really small. If a picture from a different angle would be helpful please let me know. Thanks in advance!
  3. First off good to see everyone again. Been a good yr so far with fossils this year with new ones to add to collection. Time periods its hard to say except the horse tooth from 9-15000 yrs ago. Don't mind the mod podge on the connected spinal columns (I think) because the petrified black worms or seeds creeped me out. The coolest I think the petrified grass or leaf, but other finds especially the bones are up there too. Well enjoy and good to be back and if ideas on time frames give it a whirl. PS: Ill post more pics tomorrow with sizes to show how small some of this stuff is and etc.

    Aquia Formation Bone Fragment

    Here I have attached pictures of a recent find I made in Maryland’s Aquia Formation. It’s a Paleocene bone from what I think is a turtle. What do y’all think? It’s very thin whatever it is.
  5. In Colorado there is a formation called the Dawson Formation also known as the Dawson Arkose Formation. The most common fossil by far is petrified wood and although I haven’t found any vertebrate fossils from dinosaurs and mammals have been found. It covers a relatively large time span from late Cretaceous to early Eocene, about 70-54 million years old. A member that has also found fossils in this formation, Blake @FossilDudeCO. Although it has been over three years since he was on his posts have still helped. He said that further south is Eocene but higher north in Parker and Aurora is Cretac

    Maryland Paleocene sand tiger tooth

    I found the tooth below a couple of months ago at a Maryland Paleocene (Aquia Formation) site. Am I correct that it's Hypotodus verticalis? Thanks in advance for your help! The tooth measures just under 28 mm on the slant.
  7. I was eager to get out before the heatwave coming up so I made the visit to a couple new Cannonball sites the other day as well as property adjacent to where I collected the crabs this spring. I was expecting more good bivalve material from the first sites but I'm pretty happy with the results regardless. Sort of a continuation of this topic. I tried a few cuts before working my way down to the area I found the concretions in before. The material in all was extremely fragmented. I still need to bust that concretion. One of the inconspicuous cuts. More fragments.
  8. Going back several decades I have attempted to have an annual extended field trip; call it a fossil collecting vacation. Some years this happens, some it doesn't but this past November I had the opportunity to spend several days in the field visiting some of the classic Cretaceous and Paleogene river sites which abound in Alabama. Since I haven't had the opportunity to post much in my blog, I decided to post pictures from that trip here as I have time. First up are pictures from the lowermost Maastrichtian (~70 mya) Upper Cretaceous Bluffport Marl Member of the Demopolis Formation.
  9. I'm looking for a copy of Vertebrates of the Cannonball Formation (Paleocene) in North and South Dakota Alan M. Cvancara & John W. Hoganson Journal of Vertebrate Paleontology Vol. 13, No. 1 (Mar. 18, 1993), pp. 1-23 (23 pages) It's on Jstor but isn't currently available for free online reading. If anybody has a PDF I'd appreciate it.

    Douglas Point 6-16-21

    Drove down from Jersey to Douglas Point on Tuesday. Only my second time there, and I was worried that I'd make the 4 hour drive and it'd be crowded. Only one car when I got there around 1pm, and another pulled up as I was unpacking my gear. The narrow beach was pretty much open as the first vehicle was a family wayyy down over to the left playing in the water with a raft and the other was a lone fossil hunter hand searching the tide debris line. Beautiful day and I guess my take was pretty much around average for the site. I'm quite fine with that and I look forward to returning. Mo

    Douglas Point 6-4-21

    I went out to Douglas Point (Paleocene, Aquia Formation) in Maryland yesterday to see what fossils the recent rains helped bring out. I tried last weekend as well, but I didn't find a ton as it was too close to the storms and the Potomac River was running choppy and high with little beach exposed, even at low tide. Yesterday the water was calmer and lower and I had a more successful hunt. It's definitely the time of year for snakes! (They're almost all non-venomous around here.) I encountered this one a few minutes into my hunt and saw four others throughout the day.

    Paleocene bone

    I found the small bone below yesterday while out at Douglas Point in Maryland, which exposes the Aquia Formation (Paleocene - Thanetian). It has the look and feel of fossilized bones from the area and it passed the burn test, so I'm fairly sure it's a fossil. This is the most complete bone I've found at this site. Any ideas what it might be from? Side 1: Side 2: Side 3: Side 4: Ends:
  13. On the 1st I had the opportunity for another trip and made it out to Morton County. I was waiting until now to post the report because I wanted to finish preparing a crab to include in the report but I've been busy. I went to one Fox Hills Formation site but mostly I had sites lined up from the Paleocene Cannonball Formation and some Fort Union Group formations. Compared to Emmons County across the Missouri River there is less Fox Hills Formation and it is replaced mostly by the overlying Hell Creek Formation and Paleocene units. Some scenery showing outcrops of the Cannonball Form

    Douglas Point Shark Tooth ID Help

    Went out to Douglas Point (Potomac River, MD, Paleocene, Aquia Formation) on June 5th, first time taking the kids and we had a great time. Found a lot of sand tiger teeth as is typical. But this one has me a little stumped. The crown seems too wide at the base to be a sand tiger tooth. Could it be a small or juvenile Otodus? Or is it some kind of sand tiger after all?

    Otodus obliquus parasymphyseal?

    I found this perfect little tooth today along the Potomac River in Maryland (Paleocene, Aquia Formation), which I think may be an Otodus obliquus parasymphyseal. The root isn't as oversized as megatooth shark parasymphyseals I've seen posted elsewhere on the forum, but it sure looks like an Otodus, is laterally compressed, and is quite tiny compared to other Otodus I've found. @MarcoSr, @siteseer, @Al Dente, and others, what do you think? This tooth bears similarities to another I found from this location several weeks ago (tooth on the right
  16. It's been a long while since I've had the opportunity to go hunting - indeed, trips have been far and few between. But the few I have had have been lucrative. There's been quite a bit of new material, ending up with some new finds (for me, at least.) One of these was a complete ray mouth plate. A couple Otodus jumped into my hands as well, including this perfect one, about an inch. The wildlife was out in full, including a dog that must have been born into the hobby Thanks, FA

    An Otodus kind of day

    I made a trip out to Douglas Point today and had one of those incredible fossil days that just makes you want to head out over and over again. There were two cars in the lot already when I arrived early this morning but their occupants must have been up to something else because I never saw them and I had the beach all to myself for most of the day. It was a chilly but beautiful morning on the banks of the Potomac. There's just no better sight at Douglas Point than a nice Otodus obliquus tooth waiting for you in the sand.
  18. This riker mount displays the best shark teeth that I collected on 3 hunts sifting at Douglas Point beach, Charles County, Maryland. This is the Paleocene Aquia Formation. Bottom row contains several Odotus teeth. There are many goblin shark Anomotodon and sand tiger shark Carcharias. Also appears to be one pygmy white shark Paleocarcharodon in lower left corner.

    Purse State Park 4-5-21

    I was able to get out to Purse State Park this morning for a Maryland Paleocene (Aquia Formation) hunt. I usually prefer the nearby Douglas Point when I hit the Potomac River but I decided to give Purse a try as I haven't been to that stretch in a while. I was the second car in the lot but first on the beach, which is always the best way to start the fossil day. My first good find--a croc tooth, though the enamel is very worn: Followed by an Otodus -- also quite worn but a decent size for the site (approx. 1.25"):
  20. I've wanted to put together an artificial tooth set of Striatolamia striata from the Aquia Formation in Maryland for a while given the abundance of that species in the formation. Until recently, though, I was missing a lot of the less commonly collected tooth positions--extreme posteriors, intermediates, and first lower anteriors. After searching through several gallons of Potomac River gravels over the last couple of months, I finally filled in the gaps. I put together the tooth set below a few days ago and just finished mounting them in a riker box I received in the mail yesterday.

    Unusual shark teeth

    I went out to Douglas Point (Paleocene, Aquia Formation) in Maryland yesterday and found a couple of unusual shark teeth. The tooth on the left is about 1.5 cm long and I'm pretty sure is a pathological Striatolamia striata. The tooth on the right looks a bit like an Otodus obliquus or Cretalamna appendiculata to me. Since it's only 1 cm long, Cretalamna might be the better guess. I'd appreciate any thoughts on the IDs. Thanks! Here are some more views of the sand tiger on the left. The root is both relatively large and very flat. It appears to be chipped i

    Douglas Point 3-7-21

    I made it out to Douglas Point on the Potomac River yesterday morning for a chilly Maryland Paleocene (Aquia Formation) fossil hunt. Temperatures started in the upper 20s Fahrenheit and eventually climbed into the more comfortable 40s though by that time the tide had substantially come in. The banks of the river were ice free but the sand was hard packed and frozen. The pickings were fairly slim by this site's standards, which means I found dozens rather than hundreds of shark teeth over roughly 4 hours. No spectacular finds on this trip, though I found a decent enough variety, and

    Purse 2/25 - So-so finds

    Managed to get out last week to Purse to collect the low tide. After talking to a couple of nice game wardens at the lot, I headed down to the river. Turns out I had the place to myself. Conditions were very good and the sun came out after a week of nasty winter weather. My hopes were high! Well, being in no particular hurry, I was able to look at every square inch of beach and every slump pile. But I didn't find a lot, and nothing I found was spectacular. I did collect a few pretty teeth and some bits of bone, but nothing big. Just one of those days. I did share some teeth with a lady and he

    Mystery jaw - Maryland Potomac

    Found this cool little jaw fragment last week on the Potomac in a section that has mostly Aquia paleocene exposure but also has some eocene and miocene. There is a very tiny unerupted tooth in one of the sockets which I hope will help with ID. It's hard to get a good image but the tooth looks flattish with a rounded tip, not conical and not pointy. Any ideas?

    PG county Aquia (one more time)

    I was going to do some more exploring of new areas (trying to find a Calvert exposure until I can get the boat in the water since everything’s closed) but I decided to go back here yet again. I made a pretty good decision I think because I found a bunch of shark teeth that are of decent size, and a killer shark and fish vertebrae. I also found a small block of Calvert formation here too, and I found a lot of it exposed on another piece of land a few weeks ago, but then turned around after seeing a bunch of “no trespassing” signs posted all up and down. Go figure. So until I find anot
