These are not the greatest I can clear them up by finding better size they blurred a little after resizing these pictures are taking on my property in iowa we are clearing away the land thought I should wait to do anything to these

Hi everyone, I would like to ask about these ray teeth from Calvert Cliffs. All I know is that some of them are Aetobatos I think. Thank you.

Hello Everyone! Seems to be a good bit of interest in this topic, so I thought I’d make a little summary on what types of crocodilians you may find along the Calvert cliffs. Most of this information is gleaned from Dr. Robert Weems’ “Crocodilians of the Calvert Cliffs” in Geology and Vertebrate Paleontology of Calvert Cliffs, Maryland, USA, available freely by clicking the underlined portion. I encourage you to read that for more detail. If you have anything to add or you notice any mistakes, please let me know! Thecachampsa This genus is the only described genus along the cliffs, of which two species are described in this area. Among extant (living) creatures, it is most closely related to the false gharial. All large non-shark coprolites along the cliffs are assumed to be produced by Thecachampsa. Their vertebrae, like all reptile vertebrae, have a convex side and a concave side, making their vertebrae look like they have a ball and a socket. Their osteoderms are distinctive, with thick, blunt sections between the pits. Osteoderm associated with T. sericodon, from “Geology and Vertebrate Paleontology of Calvert Cliffs, Maryland, USA”

So recently I took a trip to the Jurassic coast in the nearby county of Dorset and I decided to share it with you and record it which I haven’t done before. The location I chose was Bathonian, Jurassic and was the Forest Marble formation. I’m sorry if my fossils seem a bit crude because I haven’t cleaned all the rock off them yet. Most of the fossils in this location are found by either processing the rock or looking on the big limestone boulders which are crammed full of brachiopods and bivalves. As I said, there are plenty of shells but the eventual vertebrate remains do turn up. Particularly sharks, fish, reptiles, amphibians and I know that this location is famous for its mammal remains. Here is a picture looking towards Eype and Thorncombe Beacon and I think that’s Seatown, Charmouth and Lyme in the distance .

Hello, I have been doing some fossil hunting at Bay Front Park (Chesapeake Beach) -Brownies- in Maryland USA and have been trying to group and identify some of the teeth I found. I believe these teeth are Miocene and my guesses are as follows- what do you think? Thanks Row 1: Physogaleus contortus Row 2: Galeocerdo aduncus Row 3: Hemipristis serra

I recently moved some of my collection and noticed something loose on the bottom of the drawer under a barnacle. It's from a trip to the Calvert Cliffs in Maryland nine years ago. As I looked closer I noticed that they apparently came from inside two of the barnacles. Is this a fossil that I had dismissed as matrix, or is it a modern insect addition ?

Yesterday (January 2nd) was only my second trip to Calvert Cliffs. I'm pretty new to fossil collecting, but thanks to the wonderful advice and reading the greatly informative posts from members such as @Darktooth @FossilsAnonymous @WhodamanHD @racerzeke @KimTexan and @paxhunter I had a lot of success and it was a much more productive trip than my first. Below is a brief summary and some pictures of what I found: I woke up, put on a few layers clothing, and had my coffee at 3:45am. After my morning pipe (tobacco...I actually make briar tobacco pipes as a hobby) I got in my pre-loaded truck and headed south at 4:45am. I made good time on the drive down as I hit 695 and got around Baltimore before the morning rush. At 7:10am I arrived at Brownies Beach and pulled in to a parking lot with only two other cars in it. After putting on my full waders, I grabbed my sifter and headed towards the beach. I planned this trip so that I could arrive midweek and get there early enough to catch some of the low tide (tides times were not friendly this week, but I start teaching classes next week so it was this week or wait until spring). Sunrise was at 7:24, but there was more than enough light to see...and what a sight it was. When I entered the beach area the tide was way, way out. I couldn't believe how far out it was, as it was past two small sandbars (if I get my GoPro video edited I will post it). Once I was on the beach I headed south towards the cliffs. I hurried through the beach area because I wanted to be by the cliffs with the tide so low. I know I missed teeth along the beach, but I wanted to get to the cliffs with the tide being so far out where I could hopefully find some larger teeth than what are common at the beach area. As I neared the end of the beach I ran into one woman who was there just to relax and walk on the beach. We said good morning and I knew who one of the two cars in the parking lot belonged to. Once I went around the point and turned my eyes close to shell line and started looking. Because of all the wonderful advice from this forum I had a much better idea of what I was looking for and how to best look. After a few minutes I had some ray plates, very small teeth, and my first ever vert. It wasn't even 7:30 and I knew it was going to be a good day. As I made my way down the shore line that I figured had been pretty well picked over from people being off over the holidays, I remembered a forum member saying 'you need to look in the places that others don't'. I approached a fallen tree that I remembered from my first trip a few weeks ago, and with the tide being so low almost the entire tree was exposed so I got down on my hands and knees and started looking at some of the gaps between the tree and sand...then it happened. You know when you day dream and picture yourself finding a great tooth or fossil? Well that's what happened as my eyes saw a pristine Mako just laying there (pictures below). I know its not a huge tooth or a meg, but to me being new to the hobby this was completely awesome and a trip maker. I think I still have a smile on my face from finding it. As I continued down the beach I collected many more teeth from various sharks. I couldn't believe it when I found an awesome cow shark tooth (my second trip maker) laying out in the open about 8 feet up the beach. Beside it was another good tooth as well that went in my pouch. Around 10:30 I ran into a very friendly gentleman and we chatted a bit. We talked about the weather and the cliffs, what he had found (a few hemis), and he told me a story of a fall he had witnessed a few years ago that was too close for comfort. A chunk of clay the size of a car fell and nearly crushed him, but luckily he heard some soil falling and he ran straight out into the bay right before the cliff fell. Although the clay chunk did't hit him, the water threw him up into the air when the clay hit. His friend who was a down the cliffs said he heard it and it sounded like a car crash....I didn't get this gentleman's name but I feel like I read his cliff fall story on here, so if you know who it may have been please let me know. I continued south until the tide started coming in pretty far and I thought it best to head back towards the beach since I didn't know how far it would come in or how high the water would get. I continued my search along the way back and made it to my truck around 2pm. I took a short break, ditched my sifter, texted my wife, checked email, watched a truck with two high school kids pull in to smoke a pipe (although this one wasn't filled with tobacco), and headed back out for one more quick trip down and back as the tide started to go back out. It wasn't until about 3:30pm when two more local fossil collectors came up behind me and we said hello and chatted. All in all, I only ran into 3 other collectors during the day so there was not a lot of competition (although I do like the interesting conversation). After finding a few more teeth and interesting fossils dusk approached and I headed back to my truck. After putting my gear away and changing into some dry clothes I started my trek north after a fantastic start to 2019. Below are some pictures of my finds from the day. I know what many of the teeth and other fossils are, but if you can ID something that a newbie like me probably wouldn't know then please do so as it will help me get better with this hobby. Thanks!

Yesterday I followed the stream that starts in my backyard to the bay. Went north a bit and saw what looked like a piece of lignite in a small slab of cliff about to fall, tapped it with my machete(needed for clearing brush, spider webs, maybe a copperhead Lol!) and it made an unexpected clink instead of the mush that lignite usually is. My extraction method would probably make you guys puke but yes, I used my machete to slice until free. It was high tide, waves splashing against me and cliff, also had two impatient boys and two dogs in tow so it was quick and dirty. Anyway, it ended up being a pretty large bone. Probably whale/dolphin rib, maybe flipper?? IDK... Looks like some sort of joint at one end. Kinda wonder if a whole skeleton is buried in the cliff????
