  1. @DevonianDigger found this beauty before @Kane could get to it! @Kaneworked hard to dig this slab out but @DevonianDigger cracked the slab open before he could! Hence the new phrase (after his name) is: You've been Jayed! @DevonianDigger didn't even know it was from his pile. What a find!

  9. Howdy folks! So took advantage of a beautiful friday afternoon with my girlfriend. Went for a hike on the river bed that I usually sport alone. She hasn't found any fossils/fragments before so I was more then willing to help her find her first. Came up with a couple finds, Pictures posted below. One coral and another a fragment of an Ammonite. I tried getting the best possible shot i could with my phone camera for the colours on this piece. Pictures do no justice when it comes to the array of colours this piece emits. Then for lunch we settled down for a little wiener roast by the stream. As she was finishing up her lunch, I walked to a near by eroded hill. I stumbled upon a ton of calcite crystals.. no fossils but still very unique to find around here.

  13. Gettings, I was recently visiting the north coast of the Balearic Island of Menorca and what I found there was a moon like landscape formed apparently between the Cambrian and the Devonian period, the area of the island is called Favaritx in case someone feels interested and I saw this strange drawings at some rocks, which I suspect that may be ichnofossils or trace fossils from echinoids or molluscs... What do you think? Thank you very much.

  15. I just spent the past few days digging up some neat Devonian-era fossils from the Penn Dixie Hamburg, New York site and have two Greenops and 10 Eldredgeops that need prepped. Would anyone out there be willing to prepare these fossils for either a fee or for some of the spoils? I have a lot of high quality Eldredgeops, cephalopods, bryozoans, and crinoids that I could give up in exchange for the fossil preparations. I also have a bunch of shark teeth from Calvert Cliffs along with some neat shells (Turitella and Ecphora). Send me a personal message if you're up to the task or respond if you have any referrals.
  16. Hi brachiopod lovers I wonder, is someone in this forum interested in exchanging fossils? Maybe this is an interesting proposal for you: I have devonian brachiopods from France, Belgium and Germany and some nice ones from the jurassic of Spain to offer. There are a few miscellaneous fossils too, for example neogene and devonian gastropods, shark teeth from Germany and cretaceous echinoids from Spain. I´m looking for devonian brachiopods, without any preferences. (But any other devonian fossils are welcome too). If you´re interested, just send me a PM. The attached pictures show only some examples, there are 56 pictures with 43 different brachiopod-taxa. I prepared a small google-album and i will give you the link ;-) Cheers, Nils
  17. Found some amazing stuff today with @Kane @ischua @DevonianDigger @Fossildude19 and @drobare We hauled some serious rock and had somewhat of an assembly line going with splitting and processing the pieces. It was a really solid day all around and everyone walked away with some sweet finds. The following is a sample of some of the cool stuff I've found. The rest is packed away. The first is a large cephalon and will look good despite not having a body and then there's a Spyroceras cephalopod that might benefit from some very gentle prep work. I really like cephalopods because of all the neat chambers they contain.
  18. I've already posted a picture of this one in the fossil trips section, so my apologies for the duplication. I'm seeking confirmation that this is indeed a Bellacartwrightia whiteleyi. He's a bit beat up, missing eyes and a pygidium (or it may be hidden beneath the matrix), but what leads me to this conditional assumption is the (1) raised spines on the axial lobe, and (2) the longer and somewhat broader genal spines than what one finds on a Greenops. I just want to get the label on this one and put any uncertainty to bed. My thanks for ID assistance!
  19. Hi all. This is my first post to the ID forum. I'm stumped on this one. It was found near Kingston, NY. Comes from Middle Devonian Hamilton Group (probably Marcellus Fm). Matrix is a brownish-gray shale. It's a mold of something with small branching (or budding) tubes, dense transverse rings, terminating in cone-shaped depressions. My first guess is some form of branching rugose (horn) coral, where each terminal cone is a corallite. But I wonder if it might also be a sponge -- though sponges usually don't preserve like this, right? In the pictures below, the scale bar has divisions of 1 cm, and in the last photo there is a penny in the background for scale. Thanks for any ideas... Bob
  20. Hi, My family co-owns some property along the Cacapon River in West Virginia, and we often find small fossil shells in great numbers along the roads and creeks. Here are a couple pictures for reference, I think they're Brachiopods? There are tons of rocks like this in the area, most of which are brittle shale. You can find them just about anywhere, but they're most common on the banks around small creeks. The shell impression on the bottom right of the second image was the largest fossil we'd ever found there, but within a few minutes we stumbled across something similarly sized that we've never seen before. It's about four inches long, segmented, and tapers toward the end. Up close it has a very fine texture pattern that reminded me of coral. A volunteer at our local library seems confident it's the impression from an Orthocone shell, but I wanted to be certain. Can anyone give us an ID? Thanks very much!
  21. Found this in the scree of a road cut in what I think is the Ithaca Formation (early upper Devonian). It's a bunch of overlapping crinoid stems, right? There is a quarter sitting on top of the rock for scale. Thanks in advance, Matt
  22. Just another hike with some more finds! Another great day in my books
  23. Hello all. The other day I was sitting in my car for a day trip out of town, and with me I brought one of the fossil books I love to read. I spent the whole hour or so drive looking through the pictures of the book that gave identifications for various species of fossils, however looking at the pictures I started to think to myself how none of the fossils I've ever found in the field really looked like the pristine specimens pictured in the book. That got me thinking into starting this little thing, a (not yet complete) photo list or guide of different brachiopod species as I've found them in nature, without any prep other than a light washing in some cases. I don't know of how much help this will be to people who've been in the hobby for several years, but it's my hope that this will help new comers identify their finds and learn that more often then not that beautiful shell you see in a book is not what you'll find. In this I've compiled a variety of brachiopod species that I've encountered over the span of nine years hunting in Maryland, however these brachiopod species can also be found in neighboring Pennsylvania, Virginia, West Virginia, New York, New Jersey, and elsewhere. For the most part these all come from Maryland or Pennsylvania and were personally collected by me, however for some of the Ordovician specimens I've had to resort to photos of brachiopods I've found in the Maquoketa Group of southeast Wisconsin a few summers ago (I've only photographed species I've seen recorded from the Ordovician of the region). This is not meant to be a comprehensive list of every species, but rather an introduction to some of the more common ones that collectors are most likely to encounter.
  24. I found this in the Devonian Mahantango Formation from a road cut in western Maryland. Is it a fish tooth, and if so, what genus or species?
  25. Three Mondays in April and May, 4/25, 5/9, and 5/16/16 this writer explored a small privately owned quarry north of Morrisville, NY., Madison County. Exposed was the Mottsville Member of the Oatkacreek Formation which represents the uppermost part of the Marcellus Shale which is the lowermost part of the Hamilton Group (Middle Devonian).
