Part three to my safekeeping series. These are some of my finds from the middle Devonian Mahantango Formation of Maryland. Unlike the other formations I posted about, this one is pretty well known for it's fossil contents, so I will keep the introduction and background brief. For those who don't know the Mahantango is a middle Devonian aged marine shale that's part of the Hamilton Group in Maryland. For the most part it's fauna is dominated by brachiopods, but occasional gastropods, tentaculitids, and other animals show up as well. It was deposited in a shallow inland sea with the depth of the sea varying over time. This is only a small fraction of what I have, but it's some of the best. Image 1: Spiriferid brachiopod, Mucrospirifer mucronatus? Image 2: Some odd fragment (possibly trilobite related?) with a M. mucronatus. Image 3: M. mucronatus.

Hello i found and removed this small fossil from the rocks in Newcastle, NSW Australia. Is it possibly a gastropod?
-
Acquired two new ones today, nothing heart-stopping but just nice to have (and a change from trilobites). * A 6ish cm Knightia eocaena * A plump, mature Platyceras from Sylvania, Ohio (close to golf ball sized).

Good morning, all. Here's a few I've been working on today. Found in sw florida, I think I'm in part of the Tamiami formation. Anyway, I think the little snail is possibly Nassarivus Quadredentatus, but not sure. The large grey I think might be Nodipecten, also not positive. The ones that look like little elephant feet I'm pretty sure are a type of coral, but I can't find a match so I could be wrong. The little "toothed" thing I'm thinking is a steinkern, but would like to know for sure, and from what type of critter. Is the button a sponge? And then there's the wormy looking thing, or shell rim? There are 6 objects shown, shots with multiple angles are grouped together. Any help would totally be appreciated!

Hello everyone, I found the following fossils along the cost of Lake Huron in Ontario last weekend, and was hoping I could get some help identifying them. I've tried guessing at what they are, but I'm rather inexperienced with this. I also have no clue as to the time periods, sorry! The first one I assumed was some kind of gastropod

Hello there! I visited @Malcolmt yesterday and he was nice enough to clean up some of my stuff from Penn Dixie (mid-Devonian), including the specimen below. I'm not exactly sure what it is, so I was hoping that someone out there will be able to help me with identifying this little guy, which I think is either a gastropod or a ammonoid - what do you think? These are all pictures of the same specimen, just from different angles. And it's pretty small - only 5mm across at its widest point. Maybe @DevonianDigger can help? Thanks for your help! Monica PS - We found a definite gastropod - a Platyceras of some sort - just barely exposed on the side of one rock, but it's kind of twisted and weird-looking, so Malcolm is going to work on it a bit more - after it's done, I'll post pictures of that little guy, too.

Snail, Siphonalia devexa Middle Miocene St Leonard, Maryland Choptank Formation Drum Cliff Member Excavated from landslide material NW of Matoaka beach access in St Leonard, Maryland© Heather JM Siple 2018
-
Excavated from landslide material approximately 1/2 mile nw of Matoaka beach access. Found 4 that week. Two survived excavation. This is the only one discovered intact.

This specimen shows the original sheen and probably original coloration of the shell. It popped out of the matrix as you see it and required almost not cleaning. This specimen was stabilized, but stabilization did not change the appearance at all. Excavated from a chunk of matrix fallen from the cliffs into the Chesapeake Bay. Donated to the Delaware Museum of Natural History.

Collected in landslide material in the Chesapeake Bay. Donated to the Delaware Museum of Natural History.

Due to the extremely fragile nature of this specimen, and the species in general, I was loathe to clear out any more of the matrix from the interior of the shell, so bits and pieces of other shells are present. The large central piece is the inner "cup," which attaches to the "saucer" at only a very small point in the tip. Collected from landslide material in the bay. Donated to the Delaware Museum of Natural History.

Collected on the beach after a storm. This is an index fossil for the Drum Cliff member of the Choptank Formation, Shattuck Zone 18. Choptank is the dominant formation at Matoaka Beach. Donated to the Delaware Museum of Natural History.

I am going to preface this with a definitive statement. I know nothing about non-Devonian gastropods. I obtained a rather nice shell collection recently with hundreds of really quality shells. As I was sorting through them, I came across this one which would appear to be fossilized. It has a very matte, chalky texture, and shows signs of having spent some degree of time not alive. That being said, I will restate my previous assertion that I know nothing about non-Devonian gastropods. From some cursory research via image search, it would seem to be a Calotrophon. If anyone has any thoughts, that would be super! Thanks in advance! P.S. I apologize for the photo quality. My phone has pretty pathetic depth-of-field at close range. -J

An uncommon specimen. Identification welcome!

This past weekend I stopped by Glenerie, NY to look for some Devonian braciopods and gastropods. This was a very cool location as many of the shells, preserved in silica, weather out of the rock complete and ripe for the taking. Thanks @Jeffrey P for suggesting the location! I plan to spend much of this summer exploring the fossil localities of NY and this spot was certainly a great introduction. Here are some of my finds. Brachiopods

I found this shell cast on Honeymoon Island, Florida, USA. As you can see from the photos it's a complete shell cast and measures about 4 x 3 1/2 inches. I did some research and found similar pictures that looked like Turritella Shell. Would the Forum agree with this ID?? If so I read that this is an extinct species of fossil sea snail. Is this correct? I appreciate your feedback. Thank you!

Collected on my first trip with The New South Wales Fossil Club. Gastropods aren't common from this location so I was pleased to find it.

I have a hunch about these, but I felt it best to get some more seasoned input. The first two are trilobite partials. I'm tempted to call the one on the right just another small Isotelus, but the segmentation doesn't appear quite right. Found in the Lindsay Fm. The second image is a matter of dispute (or so I was told) with one expert stating it is an ammonoid, and another stating it is a gastropod. Found in the Whitby shale. About 5 cm in diameter.
