The 1st few may be the strangest rocks I have found. Appreciate any input. Thanks! Rock 5Rock 6 & 7: could these be fossilized tree roots?Rock 7 - external surface Rock 7 - close up of internal side (smooth) side Are the following specimens too weather worn to make a general ID? I know they are pebble-ish, but on some, there are potentially ribs (very worn), etc. I’m wondering about echinoids, ostracods, possible small brachiopods. Potential bivalve?

Found in some Paleozoic chalk and limestone gravel along with crinoids and brachiopods.

Found in Crane Hill, AL (Carboniferous) Could the (presumed) burrows be part of an Asterosoma sp? Thanks for looking

Hello, I am hoping for some input regarding some recent rock finds in an area recently exposed after heavy rains & flooding. I will probably split them up over a couple of posts. Appreciate any help in understanding these rocks. Location: Vestavia Hills, AL Paleozoic (from Ordovician to Pennsylvanian) Rock 1: Object just left of center- Bivalve? Trilobite? Rock 1: dark areas are moss - creating a bit of an optical illusion in the photo. Rock 1: close up of area on top right of rock 1, Shiny brown with white outline with some type of inclusion. Rock 1: close up of brown shiny area with white outline on front side. Resin? Rock 2: Weathered Bivalve? Rock 2: Different viewRock 2Rock 2: Backside Rock 3: could this be part of a trilobite?Rock 3Rock 3Rock 1: sorry I can’t figure out how to move photo to the rest of the photo group

Tiny crinoid columnals. Coming back to the same beach with a sieve tonight.

Found these two fossils? In some limestone brickwork. What are they?
SilurianSalamander posted a topic in Fossil ID
One is pyritized and I have no clue what it is. The other I’m thinking is a plant? Found alongside loads of crinoids

How rare are phragmocones from cephlapods? Are they something you need to get into a quarry to find, or can you recover them out of roadcuts? This is for the Midwest, like Illinois, Wisconsin etc.

Never seen this texture on a brachiopod or bryozoan before. Found in Wisconsin gravel.
-
I’m legitimately lost as to what this could be. Devonian, Milwaukee formation. Fish tooth plate?

Not just teeth and shells: my fossil collection also includes trilobites, the real protagonists of the Palaeozoic era. The first is a beautiful specimen of Morocops ovatus. Detail of the cephalon area:

Hi! Looking for help with IDs & also What is this type of fossil called (counter-impression? cast?). Specimen from Crane Hill, Alabama. Thanks for looking Pics 1-plate overview- several potential invertebrates? 2- Potential invertebrate? Some of my newbie guesses: Trilobite (side view) Eurypterid- can’t find definitive info about if locale only had the giant type Crinoid (eg saggital view) Bryzoan Gooseneck barnacle- not sure when these appeared 3- same critter, different angle 4-other invertebrates? 5-stellate shaped imprint? 6-another area of plate showing black ‘spots’ 7-black ‘spots’ look angular, maybe cubic) on high power. No idea if or how this helps, but I wanted to see if it was mold (seems less likely). Included pic for fun (apologies for the quality).

Found last week in small stream in my yard south of Bham, AL which contains mainly early/mid Paleozoic era and potentially some late. This specimen resembles a crab fossil specimen from AL, but the time period doesn’t match up. Encyclopedia of AL Thus, what could it be? IMO, does not resemble the pics I find for Eurypterus pinchers. Another possibility is that it could have been mixed in with landscape river rocks rocks uphill from the stream?

I saw this chunk on a sales table at the recent Rendezvous of BC rockhound clubs here on the Island. Had to have it, though I keep telling myself to avoid fossils with no provenance. Anyone recognize it or have any hunches as to ID and especially location of origin? I guess somewhere on the eastern half of the continent... It appears to be a mix of cherty and crystallized composition. Whoever owned it before didn't treat it very kindly (lapidary types)... Apparently there once was a label of some sort glued to the top, and the rough saw cut which I hope to flatten better and polish someday.

Found in yard after heavy rain storm. The last photo is prior to cleaning off thick clay -like coating. I may have overdone it. Thanks for looking:)

Found this Paleozoic echinoderm. I’ve found thousands of crinoid bits but nothing like this.

Did I find my first cephalopod(s)? Last one could be a crinoid

Burrow? Coral? Bryozoan?

Found this fossil in an agate of unknown age from a gravel pit ...
SilurianSalamander posted a topic in Fossil ID
I think it looks shockingly similar to charnia. Maybe a cephalopod, snail, or plant? What could it be?
-
Went to the local gravel pit. Walked away with this gorgeous gastropod and a beautiful bryozoan in jasper. Will be returning

What is the stratigraphic and paleogeographic range of Whitfieldoceras?
siteseer posted a topic in Questions & Answers
One of my friends has a Whitfieldoceras specimen from the Ordovician of Wisconsin. He asked me if I knew anything more about it. I didn't and didn't see much online. Does it have a record outside the Ordovician? Is it found elsewhere in the U.S./the world? I have the same question about Beloitoceras. He has one of those from the same site. I think I have one from a Minnesota site somewhere but couldn't find it. Is it known from elsewhere and did it survive beyond the Ordovician? Thanks, Jess -
Can someone please identify this fossil for me? I found it in Broome County, New York and I believe it to date from the Paleozoic era as I found it in association with bivalve fossils which means the fossil in question is likely a marine species and New York was underwater during the Paleozoic.
