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 -
This little rock is from Eagle Ford, since it was cracked I broke it open to be surprised by all the fossils in it and that I saw shiny things with color. Definitely not what I'm used to seeing! I assuming most of these have original shell, there are gastropods that are different colors, and also bivalves with different color, different sub order? Several heteromorph ammonites I think, and some kind of worm. Curious what the shiny multicolored area is, a couple unknowns, dendrite I think, and last one I'm not sure about, scaphite maybe? Appreciate any help!

A couple of weeks ago I was in Southern Florida with my wife and my sons family for 8 days. My wife, my 7 year old grandson and your’s truly. During this time I was able to get out and collect fossil Pliocene-Pleistocene shells from the Caloosahatchee Formation. Collecting fossil shells is one of my favorite fossils to collect and I love it when I find complete examples. I have been to the Peace River a couple times, and even stopped there on the way home to take a look at it, it was very shallow, there was a group of people sifting, but I did not partake.

This all started over a year ago. I was selected as Member of the Month and a couple of TFF members from Texas invited me down to the big state to collect. I primarily collect in my home region, the northeast, but I've taken fossil forays to New Mexico, Kentucky, and Germany and was willing to consider a trip to Texas and the opportunity to visit some classic fossil sites and collect fossils that are outside my usual focus. I began planning this about ten months ago, contacted potential fossil collecting partners and did my own research on fossil sites, geology, and the types of fossils I woul

I am wondering what fossils you can see in these rocks. they are all carboniferous limestone (prehaps not the red/brown one). I can see Bivalves, coral, crinoids, brachiopods (I think), And nothing else. Why aren't there other carboniferous life. (I understand soft parts go) These rocks are packed with fossils, what can a real paleotologist see?

Having returned last week from a nice visit with my son in Florida, it was time to examine the fossils that I snuck home with. Eventually, I will make a trip report, but I need to identifying my unknowns first. So Here goes, and I might as well tag @MikeR right off the bat! The next unknown appears to be sponge like. In fact the largest one ACTUALLY FLOATS in water. So these are very light weight. I couldn't find sponges in the Tamiami, so maybe my formation is incorrect. The rubbl

My girlfriend, Valerie and I were visiting my aunt in West Palm Beach, Florida. She is 90 and lives in a senior residence. I wasn't planning to go fossil hunting or even thinking about fossils. However, on our last night there, we were walking in the neighborhood to burn off a few calories when I spotted a number of fossil shells in front of an apartment complex. We spent about half an hour searching the shells for complete ones in good condition- found over twenty species. Valerie got into it too and found some excellent specimens. After that we began spotting fossil shells everywhere. It's a

My fossilized bivalves seem to be turning gold in some areas, and some parts have chipped off . Is this "pyrite disease"? Is it due to being on wooden shelving? I wouldn't say my climate is particularly humid. My great uncle gave these five to me when I was seven, so they are special and I would like to save them None of my other fossils or minerals are exhibiting these signs?
