Rare fossil clam discovered alive by Harrison Tasoff, University of California - Santa Barbara The open access paper is: Valentich-Scott P, Goddard JHR (2022) A fossil species found living off southern California, with notes on the genus Cymatioa (Mollusca, Bivalvia, Galeommatoidea).

Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadc

I joined with the hopes that someone here may know more about Natlandite fossil stone. My wife inherited a polished three piece set and unfortunately there is very little information available about it online. Within the two articles I could find we have learned that "it was first discovered in 1954 in Los Angeles, Ca. by geologist Manley L. Natland, during a small dig he made in his offices backyard. He was given a rock brought up during soil testing for an annex to the old Atlantic Richfield Building at 6th and Flower streets. Natland estimated the fossil st

Yesterday I was able to get out to Onondaga County in central NY. While I was there I got a chance to do some fossil hunting at two locations. The first was in Pompey Center, NY near Pratt’s Falls. The second location was a creek in Delphi Falls. The rock at both of these locations was the Skaneateles formation. I was able to get into a different formation at the second spot that was more shaly and had better preservation. This was my first time fossil hunting in the middle Devonian and I was amazed with the number of bivalves I found. (I’ve never found one in the lower Devonian near me). As w

So this trip report is a little late in coming, but it's because the week before last was a lot to process! Just saying it was amazing would be an understatement. The Sunday before last I found the Xiphactinus with @Jared C that I've already posted about (and plan to provide an update on as soon as I'm done writing this). On Tuesday I had a job interview at the Waco Mammoth Site, and on Wednesday I got the job! Then I spent the weekend in Glen Rose, joining other volunteers from the Dallas Paleontological Society in helping Glen Kuban clean and map the dinosaur trackways recently uncovered by

In the summer of 2020 jpc and I had planned to get together in Eastern Wyoming to collect. That trip was unfortunately aborted by the coronavirus outbreak that year. This year, that conversation resumed and a new plan for a three day excursion in June emerged. I decided to make it a two week long car trip, driving all the way from New York, a longer car trip than any I've made in the past 25 years. That would afford me the opportunity to stop at some other sites on the way there and back, plus see some family. Another big reason for driving was an opportunity to visit and collect at the Big Ce

On my eighth trip to the locality, I collected fossils at the famous St. Leon roadcut. Exposed were the Waynesville and Liberty formations, which date to the immense coral reefs of the upper Ordovician, or 450 ±5 MYA. The site was heavily picked, its erosive forces slowed during Indiana's summer heat. My drops of sweat evaporated on the sun-tempered limestone faster than I could count to ten. Despite the setbacks, acquisitions were generous. Best for last. Behold my brachiopods. The top row is Strophomena sp., the top-left sample demonstrating encrusting bryozoan. The second row is

Day One; Locality Four Tizi N'Talghaumt Pass 19th February 2019 This pass runs through a slightly lower section of the eastern High Atlas along the course of the Ziz River which snakes its way right through to Algeria. These wonderful trees are common in the Sub Sahara, but I don't know what they are. We stopped by the altitude sign overlooking the Aoufous Oasis on the River Ziz. Whilst wifey and Abdulla admired the huge palmerie oasis, one of the largest in Morocco, Anouar and I nipped across the road to see what we could find :

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
