Some recent Upper Ordovician finds at Mimico Creek, Toronto
Rogue Embryo posted a topic in Fossil Hunting Trips
First, if anyone in the Toronto area is interested in going fossil hunting along Mimico or Etobicoke Creeks, I'd welcome the company! Before I get to a couple of better finds, I'm curious to know what the black fragments are below, which I often find embedded in the shale. Can someone please give me a clue about these? Some orthoconic cephalopods: The next two are the same fossil from different perspectives: Some bivalves: Bryozoans:- 4 replies

I was able to take another trip to the Leighton Formation today! It's been a while since I've been able to visit (months and months), but I've finally been able to. Unfortunately, during the winter the place is completely covered in snow and ice. Not really the best collecting conditions... My last trip there was in August of last year, and the spring has been very busy. Today it was time. It was supposed to be overcast with a chance of rain, but it came out sunny and bright. Absolutely beautiful day out. The collecting was very g

Found some nice oysters, bivalves and possibly brachiopod (?) in Cierbo Sandstone (Miocene) at about 1800 ft. elevation. The largest oyster measured near 7 inches long and weighed 4 lbs!- 3 replies

Years ago I picked up these fossils in southern Indiana. I began looking them over again recently. I'll explain what I understand about them. Matrix: Ironstone concretions Classified: Carboniferous? Location: Millsport, Jackson County, IN; Muscatatuck River bed I found these fossils below the Rte. 135 bridge over the Muscatatuck River, which runs at the base of a large hill south of the river. As I recall, the rockface of the hill is gray shale. I believe the concretions are washing out of the shale and tumbling into the river. The river runs on or near the ends of

Swarthmore Fossil Hunting Club Visits the Montour Fossil Pit
cabes234 posted a topic in Fossil Hunting Trips
Hello all, yesterday I led a trip to the Montour Fossil Pit with several other Swarthmore students as one last fun thing to do before final season begins and everyone gets consumed by work. We had 5 people in total including myself there and we had quite a good time. Currently I am in the process of receiving images of everyone’s finds and several students want their stuff ID’d so I have a post for that under the proper section to get their questions answered but I thought everyone would enjoy a more general trip-report style post, I will update this post with other people’s finds as they come-

Colorful Cretaceous shells and multiple Inoceramus species (I think) please help with Id's
Lone Hunter posted a topic in Fossil ID
Had a blast last week busting up marl in the creek with Rockwood's help . I was amazed to find a chunky plate filled with beautiful shells in addition to gobs of gastropods in the area and Gryphea. Got thrown off trying to ID by color duh, finally shape of striped ones clicked, flat sides, Inoceramus sp.? The tiny brown one Inoceramus cuvieri? And the little round ones pinnaeformis? The tip is broke off one but they are all the same. Limestone Inoceramus maybe labiatus or sp.? So not sure about Gryphea, 2 are in piece with the big shells and one of them is round, the other right underneath- 28 replies

I recently took a trip to my hometown, San Antonio, Texas, to visit family whom I hadn't seen since before the pandemic. Ever since I caught the fossil bug last year in Maryland, I've been itching to make it back to Texas to explore. This trip's purpose was to catch up with family, but to do so, naturally, I had to catch them up on my new hobby! Two places were easy to add to my itinerary -- both my Mom and Dad have seasonal creeks in their neighborhoods, which I was able to walk. The creeks in my Mom's neighborhood expose Albian rocks from the Edwards Group.

These fossils were purchased by me from a friend who had received them 30yrs ago. In the box they were in was a paper that read "Miocene, Calvert Cliffs, MD. Though some have argued that they are Florida fossils...I found id's for all but a couple from: "Vokes, H.E., 1957, Miocene fossils of Maryland: Maryland Geological Survey Bulletin 20, 85 p". I was wondering if anyone could id the two left...the single fossil photos? Thanks Greg

Possible Trilobite and Bivalve Fossils found by side of road in Sharon CT.
cabes234 posted a topic in Fossil ID
Two days ago some workmen laid some stone by the side of a road near a pond in Sharon CT and I found two fossils one that appears to be the back of a Trilobite or a Chiton and another that looks to me like scallops or some other bivalve (I know that scallops and trilobites never existed at the same time). Does anyone have any ideas as to what these could be. Also I know this rock is not from where I found it, it was probably sourced from a local quarry so I would have to check with the highway department of Sharon to figure out where these come from.- 17 replies

The fossils were found in the 70s in northern Sardinia during the excavations for the construction of a road. I do not know the exact location, but I know that it is the north of Sardinia. The coin is 1 euro (it's similar in size to an American quarter.) What could it be? Thanks in advance

Another trip to 'gold mine', huge Gryphea w/shell, tiny Echinoids, tooth & more
Lone Hunter posted a topic in Fossil ID
Went back to my little gold mine today and was again amazed by the variety of things found. Previously I thought I was in Eagle Ford, but it is in Woodbine, with ravine that cuts down to Grayson as was explained to me in first post from this local. Everything was dried out except bottom of ravine, from the looks of things I think a natural spring is involved. So found some more Mariella ammonites, one with part of a scallop maybe?, and a Hemiaster, another Texigryphaea with some shell, I believe a little bacculite, an Echnodus tooth?, unknown clams, a Trigonia, and crawling on hands and knees -
Hello. This is my next mystery. It's been looked at in the precleaned state and dismissed as a cool rock. I beg, to differ and need your thoughts. My reasons for thinking this is a fossil/ fossil impression are as follows: 1) As I cleaned, the left edge (see ladt pick with knife), began to show evidence this is on top of the matrix, not part of it. Likely matrix of shale-chert so please, take that into consideration. Extremely odd charts in my area 2) Looking at the picture with my finger, examine that small white portion. That appears totally different from the rest.

Found a little gold mine of Turrilites, Echinoids and bivalves
Lone Hunter posted a topic in Fossil ID
I've driven by this field for years with a big ravine in the distance and decided to check it out since it wasn't fenced or posted and glad I did. The ravine was a good 30-40 yards long, probably 10ft+ at deep end and around 5ft wide, as I got closer the dirt changed to grey clay mud with little vegetation, the surface was sandy and rocky. First thing I saw was the large Echinoid, then peices of what I thought were ammonites until I found a more intact one, then I thought Turritella but didn't quite fit. Had a heck of a time trying to ID them and finally ran across Turrilites, I think that's w
