Hi Everybody! I'm glad to finally join the forums. I am a lifelong angler and outdoorsman but only in the last few years have I added fossil hunting to my outdoors repertoire. Although I have always been interested in paleontology, I didn't actually try fossil hunting until randomly running into a little spot on vacation at a Pennsylvania park with a small exposure of Devonian shale. My kids started breaking open rocks and got me into it, and there it was--a tiny clam--my first fossil. I had already heard about fossil shark teeth back home from visiting the Calvert Museum. So one day I brought a makeshift sifter out to Brownie's to give it a try. Not knowing anything yet, I went through quite a few screenloads before I finally found one--a nice little snaggletooth. But having found the one tooth, I knew it could be done. I have been fossil hunting around the DMV ever since, mostly on the Chesapeake and Potomac. I have studied up on our local geology and fossil sites, watched Youtube videos, and read this forum a lot to get fossil hunting tips. This has helped me a lot to get up the learning curve. I have had good luck and made some decent finds for my growing little collection. With the COVID lockdown, I have actually made more fossil trips than usual (as exercise!) and have tried a few new things. Now I'm at the point that maybe I can share back with the forum and not be embarrassed as a clueless newbie! Also, I am starting to have specific questions about methods, identification, etc. where I could use the help of the veterans here. Anyway, that's the basic info about me. I look forward to writing some posts and hopefully sharing some pix. HemiHunter

I've been a rock junkie my whole life. I can't help but look for minerals and evidence of organization in lithic form in one shape or other. It's a key for me to entry to learning about our world and reality. Thanks for letting me into this realm. What most recently brings here is that I have proposed and had the proposal accepted, to carve a gate based on the concept of crinoids found in the Shenandoah Valley of Virginia. As this is a fairly specific geographic area I was hoping some folks here might have some species specific information that might help me "flesh out" this concept to turn this functional sculpture into a bit of a learning tool. This will be carved from catalpa, assembled and painted. My website is https://www.sawaddict.com You can see some of my other work there. I hope to work more along these lines in the future. Hope you folks can help-Glenn

Hello! I found something I can’t get a line on, so I’ve come to the forum for help. This is a beach find from the James River in Virginia. I think most of the marine materials are Miocene, I’m not sure of the formation(s). I think this a higher likely hood of being a small marine mammal bulla, but the form is different than any others I have seen, it looks sort of like a mammal tooth, but without the root. It is mineralized, no smell from flame, and very hard, but not quite as dense as other earbone material I have found at the same site. There are traces of black harder and more reflective “enamel” especially in the pocket, between the ridges on what could be a chewing surface. It doesn’t match any specific mammal tooth I can find but it has some of that “feeling” in terms of density. Not much wear, is it possible for an unerrupted tooth to not have such a smooth form on the back. As I write this I realize how illogical my thoughts seem, and how little I know about teeth... i found a very pretty cowshark tooth yesterday too, for something a bit more recognizable. thanks for your time,

Like most of what I find these days, this is small (the scalemarks are mm). A small cylinder with diagonal pattern of markings. Seems too solid for fossil cartilage or skin? Any ideas?

Hello Everyone- Any help is greatly appreciated. I have had this (what I believe to be a fossil) for about 25 years. My grandmother found this when I was very young and I have held onto it ever since but have never taken the time to learn what it is. It was found near a creek bed in Southwestern VA. There is also a rock quarry nearby the location. Took the best images I could with the only metric measuring tool (measurements are in cm) I had on hand. If more details are needed, ple ase let me know. Thanks!

I found this piece of bone while walking a bank a few miles below Hopewell on the James River this past weekend. My Rockd app says this area is the Charles City formation. The bank here is fine brown sand mixed with small pea gravel that turns into a marsh area. I've never found much bone or fossil type rocks at this spot before as this is a place we usually search for arrowheads and stone tools at this location. However just up river a mile or two I just found a bank in the same type formation that has a very large line of vertebra sticking out of the side of the bank. There on that beach up close to the bank is an area that is 15 to 20 feet wide and at least 40 feet long that is littered with bone fragments and small pieces of vertebra then up on the bank wall that is 4 to 5 feet higher than the beach there is this line of vertebra that runs horizontally for at least 40 feet maybe more. I didn't have time to get a really good look at this site because we had to leave but I plan on going back there soon to get some pics of that site. I don't know if this bone in my pics is related to this animal up the river but I guess it is possible.

Found this cute little tooth. Doesn't look familiar to me. Somewhat similar to sand tiger symphysial but much smaller. Hoping somone knows what it is. Photo of the tooth and its v-shaped hollow(?) root (leaned against small bone bit). Thanks!

New member. Hi. Found these chunks of probable whale bone on a sod bank along the Chesapeake in Kilmarnock Va. The one on the right is a rib base. The other two might be shoulder or pelvic girdle bones.

Combined a couple of trips to the creek in the woods. Looks to be busy with the kids out of school (VA public schools closed March 23; we're in Lockdown until June 10. Local kids must be getting bored with their games and cell phones.) I haven't seen any yet but they have been busy digging, often in my favorite areas. Probably should just dig in some random spots, just to see if they tackle those as well. Has been cold lately, lot of east wind days (bad for beach hunting, higher water). So made two trips. Lots of small bones/teeth(?), skate teeth and broken teeth in mostly gravel areas , just showing the better (nothing great, although several sand shark tiger teeth had sharp cusps, and more had buttons where the cusps had worn away. ) Highlights for me were the sand tiger symphysial near the orange vert, the two small angel shark teeth, and the inch-plus root-less mako (hadn't seen any in a while). Also found a partial ecphora and a small broken cow shark tooth (just the first spike with the three small ladder of points ascending) both put away. Need to go through some other stuff more carefully after it dries.

Westmoreland State Park, VA, USA: Unidentified possible vertebrae, rib(?), and shark tooth
Bowmania posted a topic in Fossil ID
Hi all, I had a fairly productive first outing to Westmoreland State Park but I have no idea what any of the fossils I found are. I am happy to provide close-ups of any of the individual fossils, and in addition to the photos here, I posted some to imgur to get around the size restriction here. https://imgur.com/gallery/2uIedQS Thanks for your help!

I have some beautiful crinoid stem cross-section impressions from the Devonian Mahantango in PA (runs from NY to VA) and have been searching all morning to find a good reference book that won't cost me $100 just to open the cover and see if it's adequate to the task at hand. Winifred Goldring seems to have done the definitive works, but she didn't include any cross sections! Can anybody point me in the right direction?

Found this big guy in Gore. The head was exposed so I kept chipping away hoping there was more to him, and sure enough! It took about an hour to chip away the surrounding matrix, and at the end I thought I'd have to break him to extract him fully, but I pulled and he popped out! Is he deformed or just big? The head looks kind of smushed. Apparently my pics are super large so I'll try to add a couple more in the comments.

Nice weather finally. But with schools closed and people bored at home, have seen increased competition at "my" sites, but yields have been small but plentiful. Fish should be biting soon.

Hey guys, found something totally cool this weekend looking for teeth and bone in Virginia. This long thing that looked like a claw. First thought was dinosaur raptor lol!!! But I know that's not it. Anyhow a buddie here said it's a sperm whale tooth. Pics below. Also found alot of bone(whale), teeth, verts, half a small Meg, mako tooth, and a pair of fossil sunglasses someone lost! Good luck everyone.

I found this shard of bone on the York River in the Yorktown formation, and the pattern on one side is curious. I’m wondering if anyone has seen this, or if it’s a diagnostic texture? Thanks for any help!

Coldest morning here in this mild winter. Headed to the creek, almost devoid of life, although plum? trees are blooming. Water felt relatively warm. Raccoon and deer tracks everywhere. Stayed at one spot hoping for a cowshark tooth; found three, but all broken. Lots of the usual sand tiger spikes. A small delicate sand tiger syncytial tooth. Only one angel shark tooth, a dozen or so drum teeth. A skate stinger, bigger than usual but enamel only on one side. Weird vert, has a 'wing' on one side; usually verts are more symmetrical but I saw no evidence of a broken wing on the other side? No big teeth (i'm a bit overdue for a 2"er!) Fortunately/ unfortunately? no freezing weather here until Friday morning. More comfortable for hunting teeth, but bad for fruit trees and the more amorous birds. Maybe 2020 will be the Year with NO Winter?

Hello everyone from Saltville Virginia
-
Had a big rain and a major windstorm (lost power a couple of hours), even though the wind was from the south (and I much prefer winter north winds for my beach) had to check. A bit disappointing, tooth-wise although I did find a mako and a big shrimp coprolite burrow, and five small teeth (and some old pottery shards). Tried the creek at an old spot, where I hadn't had much recent luck, but the rain had deposited teeth in one spot and weakened the bank in another where I dug around and found some teeth but mostly bone bits and a few interesting steinkerns (with some glossy surfaces, one an obvious snail shell, another with shrimp coprolites.) Found one ALMOST complete cowshark tooth, four angel shark teeth and a bunch of drum 'teeth' and several sandshark teeth, plus four verts and a lot of skate teeth, most broken. Better than usual hunting. First scan is of the bigger stuff (not counting bones or shells, who asked that I pick up some for her kids): the cow shark, mako, a lemon(?) and tiger shark, plus a weird concretion, a Tilly bone and two vertebra, the top one with an odd loop. For the mantis shrimp coprolites, notice they tend to be thicker in the burrow than in the steinkern below.

Much improved weather, water cool but not bad, air temps in the 60s, lots of budding trees (but winter will return). Dug at one one spot until not finding much. Nothing spectacular, but I was delighted to find two more sandtiger shark symphysials (wish they were cow shark); in the photo next to the broken cowshark. Three or four angel shark teeth (near cowshark), lots of broken sand tiger spikes, plus some nice ones with cusps. Some grey shark teeth, a few possible small makos, and some indeterminate. Dropped a few drum teeth, but only one tiny vertebra, on the scanner. One bigger skate tooth of several, some bone pieces. Great day to be out!

I guess my first thoughts are whale bones. I have found some vertebra and a phalanx down the creek last week. These were buried in the creek wall and I believe in the Yorktown Formation. They are very heavy and have a solid “ring” to them when they touch. They’re on an 8.5” x 11” sheet of paper for size reference!

Hello! Anyone have any ideas? I believe we are looking in the Yorktown Formation in Virginia. Found right next to Lots of Chesapecten Shells. It feels like stone but is a very strange shape. Almost all the stone coming out of the layer is pebbles and somewhat rounded.
