Fossil Forum folks have been a huge help to me so far. Here is another ID request for a fossil found recently in ORDOVICIAN limestone of SE Minnesota USA fH

I've been lucky enough to get hold of halisaur skull fragments over the past few years! I'd like to start assembling them in to some sort of composite for display purposes within my collection! I would love to see any Halisaurus skulls you guys have? Especially bone layouts so I may identify where my bones fit! Thanks!

I am nearly sure the top piece is Metacoceras. The middle is a clam, but what species? Perhaps Astartella concentrica? The bottom, what is that thing? 6477/6478 show it in detail. I find these a lot. Are they brachiopods? Not shown, but there is a horn coral on the back of the piece in a cross section.

So, I have two more fossils (I think), that I could really use help with.... Both found in same location(s) and formation(s) as my prior posts. The first, looks like the impression of a mollusk/shell to me (about 3/4' in diameter) ??? The second, I cant even begin to guess as I would probably be wrong anyway. lol Its corkscrew in shape and about 3/4' long. It left a mirrored impression of itself on the opposing rock. Any thoughts???!!! Thanks in advance. :0)

Hello everyone, I had recievrd this as a part of set of many fossils a few years ago as a gif, it was labeled as an algae fossil and the piece is very interesting but I am not sure what it is and what the age could be, one side is very glossy while the other is partially so, the glossy side has very interesting coloration and I am unsure of what it could be a mineral or a part of the fossil, the other side has some staining which could also be the fossil I am really not sure but another very unique thing about this is that y the side of the rock has almost a fiberous look with lines running up the specimen. The ruler provided is in inches, Thank you very much.

I am going to start adding some images of my favorite finds which I call Collection Pieces. Identifications range from maybe, probably to most likely. I've only started to seriously collect over the past year. I've spent a great deal of time studying and learning Geology, as a hobby. I am located in Western Pennsylvania. At first, a map of the area. Anything in bright yellow is the Glenshaw Formation. The Ames Limestone layer exists between the Glenshaw and the Casselman Formations, which is the Orange color on the map. I have yet to explore the Ames Limestone, so I've only found fossils that exist in the marine zones below the Ames. Second and Third, are Metacoceras. The Fourth photo is of another Metacoceras. The id is slightly less likely as I can only see a few of the rounded spines. But I'm pretty sure it is one. Coming up next is a Mooreoceras that I found just this past weekend. I maintain everything on a website, that is listed in my profile. Thank you! Clint

Ordovician or Silurian. Pleistocene erratic boulder. Central Poland. Black, shelly object + nicely ornamented mould, which may or may not belong to the same fossil. As always - sorry for the unpreped state + poor photos. So far, I considered: Leptaena fragment, trilobite sclerite, or Catenipora in side view. Any ideas?

Hello, I find a lot of what I believe to be marine fossils from the Cretaceous period on my land up in Grayson County, North Texas, but I am not certain what kind of fossils they are. Here are pictures of what I think are coprolites? Thank you in advance for your help in identification.

I recently acquired this very lovely fossil tentacle with amazing color and nicely prepped. I just cannot figure out from what specimen this could be from, or even if it is real. I believe it is legit because it has some crystallized aspects and if it's fake it is a very good one!

Okay, I concede early on that this may be abiotic, but I just have this gut feeling that it's not an accidental pattern. I found this on the banks of the Potomac River in Virginia. The geology there is mostly early to mid-Miocene clays with a Pleistocene terrestrial bog iron layer on top of 40 to 80 ft cliffs overlooking the river. All fossil-bearing. This looks like clay, but I'm not positive that it is from the Miocene layers. There is a row of tiny lumps all about the same ship and almost in a contiguous line. One is just a little offset.

I collected with @ rwise in the Goodland Limestone, Lower Cretaceous of Cooke County Texas today. I found this semi-circular fossil that may be a burrow. Looking closer at the large end there was a dotted line, lower left. Closer... Closer... Closer... That's a mm scale and this is the best my camera will do close-in... Any ideas?

I bought these at a Rock Shop in or near Moab Utah. Pretty sure the dude said they were from around there. What do you guys think?

Was given to me as a gift. Not sure where from.

I was given this as a gift as a child. I gave the other half to a friend some time ago. Here Are the Pictures my dudes:

Im really not sure what this could be. It was found yesterday in 2 million year old fransician muds at Centerville. Im thinking some sort of plant impression. Or maybe a fragmentary piece of sand dollar which are known from this locality aswell.
-
I found this a few days ago along the Virginia side of the Potomac River along a miocene cliff. It's mostly if not all Choptank formation. Any ideas about a genus? Grid is in inches. Looks like maybe mature dolphin tailbone, but it's so small???
-
I found this scapula this weekend along the Potomac River in Virginia. It's a vertebrate. That's all I know for sure. Most of the cliff next to the beach where I found it is miocene marine, but the very top is pleistocene terrestrial. The grid is in inches.
-
I really have no idea what this is. Maybe I am missing something obvious. Maybe a nautiloid fragment? It was found in a fossil-rich hard miocene(I think) sand/mud stone. In the that piece of rock were some poorly preserved bivalve and gastropods. Lastly, what would cause those interesting markings on it? The NZ $1 coin is has a diameter of 23mm Thanks!

I found this is Western Washington state in an Oligocene Era sediment. I was thinking baculite but I have no idea. Someone please help me out. I split open a huge piece of mudstone and it popped out negative and positive (so the rock on the left is the imprint and the right is the positive). A piece broke off so I had to glue it back together

Recently re discovered a bunch of these things that we got from the Canary Islands. They were all washed up on the beaches and they do not look stricktly geological to me and looks kind of like some kind of modern calcified organism or trace of one. I stumbled upon a book at some point, I believe it was called Darwin's Fossils that said these were some kind of remains of algae that have fossilized, but when I looked that up there was no evidence I could find supporting this claim, maybe someone else knows what these things could be? Any new insight is appreciated, Thank you.

Requesting assistance identifying the dark slug-looking forms, these look like they were once soft-bodied so I'm pretty lost. I haven't the foggiest idea what these are and my fossil reference books don't have anything that looks like this in the photos or illustrations from what I can see. This was a creek find in southeast Louisiana. Your time and expertise are very much appreciated by this fossil newbie, thanks.

I think I may have found my first Devonian bryozoan. (From Sylvania, Ohio.) And I also am not sure if these are shell or plant impressions. The rock that I think has the bryozoan has many nifty whatnots to explore, but that pattern immediately caught my eye. I'm not sure if the fan shape on the second rock is plant or shell. And there's a small bit to the left of it that appears to be shell that I haven't started to ID yet. (Pics in second post) Thanks for any help.

This comes from Centerville Beach, Humboldt County California. I've found alot bivalves and snails in the cliffs where I found this. Another Formation 5 miles away has had reports of turtles, shark and marine mammal teeth and even agatized whale bones. I'm sorry about the quality of the pictures. I do not currently have a very nice camera. Its sticks to my tongue and has a rough porous surface. The divet on the right side of the bone in the first picture is a place where is has apparently broken.

Clearing some brush under an old red oak and found these
