Hello everyone, I just came back from a short trip to Florida to visit some relatives who recently moved out there. I knew very little about fossil hunting in Florida but with the generous help of a number of forum members got to learn a lot. On one of the days while visiting, we decided to visit Venice. While there I did end up picking up some tiny shark and ray teeth, interesting modern shells but nothing particularly special, once we got off the beach, though, I noticed a pile of shell material in sandy matrix near the parking lot I initially thought it was just the same modern stuff as on the beach but closer inspection showed that these were definitely fossils, they had a different texture, coloration to the modern shells, were more chalky and fragile and we're covered in matrix inside and out. I didn't take any in situ pics as I had no phone on me but here are some photos now that I have them home. Also, I'm trying out a new photography technique using an elevated glass pane I saw here on TFF, and I think it looks quite nice, really makes the fossils pop. I don't remember the name of the topic but if anyone wants to link it below, I would appreciate it as I think people may find it quite useful. Olive shells: Next to a modern lettered olive I found, interesting to see the morphological differences side by side as although they are similar the form of the shells is different Other gastropods: Bivalves: These two were connected when found, but split apart on the way home, revealing some interesting fossils inside. Two oysters, not sure if they're the same species, they look pretty different, the smaller one is complete while the other is only one valve Some tiny gastropods and bivalves, the gastropods were found next to each other in the matrix while the bivalves came from the larger bivalve that opened up finally, this I thought was really cool, it's a tiny barnacle, also from the bivalves that opened up, it's preserved in beautiful detail, you can see some very intricate details of the shell on the top and bottom of the specimen This was my first time in Florida, and my first experience collecting such young fossils, it was very enjoyable and I hope to find more stuff on later adventures. I have pretty much no idea as to the IDs of any of these fossils, so if anyone knowledgeable has any suggestions, I'd be very interested to hear. Thanks for looking! Misha

crane Hill, AL -Carboniferous Wondering if any of these could be fossils such as bivalves or brachiopods or if they are limonite concretions? Y the one below looks a bit like a lingua in person, but hard to see in the pic Would it be beneficial to try to dissect the one below? Also wondering if the area of interest below could be better exposed? Thoughts if fossil vs concretion? Thanks for looking!

Hello, I found what I think may be two fossils but I’m not totally sure. I’m really not terribly knowledgeable with all this. The first appears to be a bivalve impression fossil with at least 3 different shell imprints in the sample. I found this rock washed up on the beach at Amelia Island Florida (Atlantic side). It has several nice impressions in it. Is this a legit fossil or do you think something like concrete amalgamation? I don’t know… it just seemed really easy to find. If legit, any guess as to it’s age? The second sample was also found washed up on the beach at Amelia Island Florida. It looked bony to me based on its appearance and symmetry. Not sure if this represented some sort of fish or whale bone. Thanks again for any help!

Found in Calvert county Maryland. Attempting to figure out the Latin name but I keep getting different names online.

I’ve decided to post this one separately. Very unusual composition. If you watch the video, you’ll see that light refracts off of tiny crystals in the center of each segment (which I’ve circled in red in another image). It’s hardly noticeable. The specimen is very smooth and rounded. Another member said in a different post of mine that it could possibly be an inoceramid hinge, though my own research resulted in nothing. I can’t find anything online that remotely resembles my specimen (inoceramid or otherwise). I found it at Post Oak Creek in Sherman, Texas. FullSizeRender.MOV

Hey all, I believe I found a fossil. I came across this while rockhounding. I found this in Monroe County, Valmeyer, IL in the USA. I found it in a stream bed, with running water. Chiefly, and this may help, I found many imprints of seashells on rocks. I also found a complete bivalve (I think that is the term for both top and bottom) seashell that had crystallized into quartz. I have pictures at this link, along with a picture that has measurements in 3 forms. I tried to upload to the forum but there was issues doing so. If it matters, the surface feels bumpy and unlike any rock I've ever seen texture wise. I'm fairly certain it's a fossil..it sounds different on the darker areas when I tap on it. Thank you for any help. https://imgur.com/a/S2Fg51T

This specimen measures about 22.5cm in length and 14cm in width. I found it about 9 months ago on the riverbank along Joshua’s Creek in Oakville, near the tip of the Georgian Bay Formation that meets Lake Ontario. Been really busy the past few months, so haven’t had time to post it until now. Can anyone identify what Fossilized Bivalve species are present on the Rock?

I found this clam buried in mud along Joshua’s Creek in Oakville, near Lake Ontario, the hotspot of Ordovician fossils. Measurements are 7cm by 6cm. I’m particularly intrigued by the growth rings, since they protrude out rather visibly and considering I’ve never seen this in any other kind of fossil or living clam species. Can anyone help with identifying what species of fossil clam this is?

I have posted examples of this fossil before in ID, but this is a newly found specimen that is more complete, but still missing the same area that all my specimens are missing. Photos of the other examples and the resulting conversations can be found in the previous post in October. This example shows what appears to be hinge teeth, a muscle scar and the general form. The shell in all examples thins dramatically towards the muscle scar and the origin of the growth lines, and the missing features are always just past this point away from the margin side.

How to reduce visibility of preparation marks on matrix
ToadCultist posted a topic in Fossil Preparation
Bought this lovely green muscle a few days ago and was wondering if there's anything I can do about the white marks left behind in the matrix from preparation. I've been recommended to use a thin layer of paraloid and I just wanted to double check if this is a good idea. If so what percentage would you guys recommend. Thanks in advance!

I was hoping to get some help identifying these bivalves. They were collected from Pennsylvanian (Desmoinesian) limestones in Illinois. They appear to me to be the same form, but I could be wrong. The shells are fairly featureless. The three specimens range from 0.5cm to 1cm in width.
