  1. Hello! I came into a ton of fossils well documented from the 70s 80s and 90s. I haven't gotten through half of the boxes. It's pretty incredible!
  2. Hi all! New here so apologies if this isn’t formatted correctly or anything. I’m new to this and really want to do a fossil hunt with my family, I live in the sea coast of New Hampshire and could travel about 2 hours in any direction, I also have a house in Warren Vermont and could do the same travel time from there. Does anyone have any tips on places? Preferably easier for a beginner fossil hunter. Any tips on what tools I would need would be greatly appreciated as well. Thank you!

    Vegatable, animal or mineral?

    Hello all. New user from central Maine. I found what I believe to be a fossil in the stream in my back yard. I used an app to identify the rock as limestone. Limestone is not native to my area, but there is a source in nothern Maine about 250km away. If it is limestone I would guess it was deposited during the last glaciation of the Laurentide ice sheet. It looks like a plant to me, a whole leaf maybe. The raised " stems" are hollow and there is the round ball ont the end. This round ball has two holes which is why i thought maybe a worm. These holes are tiny and symetrical, but only able to observe them with a jewelers loop. Thanks for any info.

    A friend's mystery from Maine

    I return once again to the Forum. Recently I was asked about something which someone on Discord found in Maine. Honestly, I'm not quite sure what to think of it as I'm not entirely familiar with the geology surrounding Maine: What my Discord companion does know is the area which they found it in, right around Caribou by the local river, which appears to be underlain by Silurian strata (based on Rockd) I'd love to get to the bottom of this mystery!
  5. My wife and I are planning a trip to Vermont, new Hampshire and Maine this fall. Does anyone know where to fossil hunt or somewhere to rock hunt. We love it all? Thank you in advance

    Ordovician algae

    These were found in a boulder used as rip rap along a rail bed here in Maine. I've never seen rock like it exposed in cuts along the route, so it may have been transported some distance. These are old photos, but I've donated the best examples to a local museum (Bates Museum, Hinkley, Maine) and the label on it was destroyed. Unfortunately I can't find the post, but I'm quite sure it was identified as a calcareous algae known from the Ordovician. Can anyone help me identify it so that I can inform the folks at the museum. It's a small museum and they don't really have a paleontologist.

    Is this a keeper ?

    I couldn't quite bring myself to toss this out without checking. Is this something good ? I think it's from the Silurian Hardwood Mountain formation, but honestly I hadn't been treating it as very important.

    Bone?

    Found at low tide on the Maine Coast (an unlikely place to find fossils, apparently). Approximately 3 inches longest side. Looks a bit like the dinosaur bone I've seen from Utah, except there aren't any dinosaur fossils in Maine. Any thoughts are appreciated. Thanks!

    Leighton Fm Fossil ID - Bryozoa?

    This specimen was from my most recent collecting trip. It is from the Leighton Formation, which is Pridoli, Silurian. It was suggested by @Tidgy's Dad that it is likely a cryptosome, but I was hoping for a third opinion. The following pictures show the specimen. I have already posted some of these pictures, but have added scale (finally). The first two are of the two pieces of the specimen - I refer to the top image as the "external mold" in reference to the Nuculites bivalve next to it, and the second as the "cast". The last is a close up of the "feathery" section on the end. Thanks for reading!
  10. I finished this prep of a trilo-cephalon a week ago. I kept forgetting to post it, but I finally remembered today. This is an Acaste zerinae cephalon. It is from Leighton Formation, pre usual. It is missing a small chip of the right eye - I unfortunately didn’t notice its absence till I returned home. It’s a shame, this guy would have been completely whole if I had found it. On the plus side, this guy’s a very nice color in the sun - a kind of bluish. The other trilo-bits - including another cephalon - all were a brownish color. Makes this one a bit more special. The first picture below is of the cephalon pre-prep. All the following images are of the cephalon from multiple angles, then in natural light. Thanks for reading!

    Unknown fossil

    Fossil forum, I recently found an interesting fossil. I was thinking coral or bryozoan, but was unable to identify it correctly. It is from the Leighton Fm Maine (again), which is Silurian. Any help would be greatly appreciated. Here are some pictures of it:
  12. 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 good. I unfortunately forgot to take a picture of the site. I was working in the same spot as last time, and at another outcrop a little farther down the shoreline. Place hasn't changed much, still as minuscule and weathered as ever. I had a better idea where to look though. Last time, I collected a lot, but I was mainly working in layers where the fossils were very evident. These layers contained a plethora of brachiopods, ostracods, tentaculites and other invertebrates - plus my first conodont. This time, though, I was going to try something a little different. The layers between the extremely fossiliferous layers had finer sediments, and generally seemed to keep the specimens intact better. I chose to mainly work in what I now call the "Chonetes layer". It's the only layer in these outcrops that contain Chonetes bastini brachiopods. The layer doesn't shatter as much as the other shale, so the pieces come out without a lot of cracking. It was also the same place that I found a nice trilo-bit, and I was hoping it would pay off. It did... The best finds of the day went to the trilobite cephalons. I found two Acaste cf. zerinae sp. - mostly intact, but an eye cracked off on the first, and both on the second. I was (luckily) able to find them, and I intend to glue them back on. At least the external molds are completely intact. In all of the following pictures, internal molds come first, external molds second. Cephalon #1, the one-eyed wonder. Cephalon #2 - missing both of the eyes. Sad, it would have been so nice too... Then came the pygidia - four of them! I believe that they are all the same species as the cephalons - A. zerinae - but I could be wrong. I'm sure the trilo-experts here can help me with that. Pygidium #1, the nicest one. Pygidium #2 - this little guy got a bit beat up when the rock split. Pygidium #3 - little bugger needs to be prepped a bit. Pygidium #4 - the internal mold of this cracked in half - and it's missing a piece. This one's a neat little trace fossil. It looks like an infilled burrow to me, but I'll set up a separate thread for that - with better pictures. And this very odd little guy. Another one I'll have to take better pictures on, and as soon as the matrix is pared down a bit I will scrutinize it under a microscope. It's not very evident, but it feathers out at the right end. It could be mineral staining or something, but I'm not sure yet. Then the stuff I couldn't bear to leave behind. I was trying to keep my collecting to new stuff, but some of them just sneaked in there... I feel like we've all experienced this before. Orbiculoidea sp. brachiopod. Lingula sp. brachiopod. Leiopteria rubra bivalve. It was a pretty good day. On top of these finds, I brought back some promising shale pieces to look for micro-fossils in - and a few more interesting unknowns. But that's for another time.. Thanks for reading!
  13. In this thread, I hope to share numerous examples of the ostracods of the Leighton Formation. As I identify them to at least genus level, if not species, I hope to post them here. If anyone has a better suggestion for the id, please let me know. First up is a cast of a left valve, female, Hemsiella maccoyianna sulcata. Length is approximately 900 microns.

  15. I am really puzzled on this new one, I have explored phyllocarids, trilobites, and many others, and can't seem to find a good match for it. I am not absolutely positive it is a fossil though, just the surface texture and way it prepped makes me think it is. It is from the Leighton Fm, which is Silurian, Pridoli. When I first started prepping this, I was under the impression that this was the internal mold of a Chonetes bastini, which is why I started on it. I soon discovered though that it couldn't be from a brachiopod, and now I am stumped on it. The first specimen is completely prepped out, it is labelled SA in the photo. In the process of prep, I also found a new piece that exhibited the same surface-texture (labelled SB in picture), and could be a part of the first specimen. Below are a few pictures of it. The first is of the specimen before prep - this is the only picture I have, and shows everything that was exposed. It was taken from the top of specimen SA. The next picture was taken from above, it shows the two specimens (SA and SB) and their relation to each other. The third picture shows the specimen that is on the upper left (SA), the fourth shows the specimen on the lower right (SB). Thanks in advance for your help!

    Phyllocarid valve?

    This morning I split this shale (technically it fell apart on me), and found this interesting little fossil. I was thinking that there was a possibility of it being a phyllocarid valve, but I have never seen one. This also raises a question that I have been wondering - how do you differentiate between a phyllocarid and a bivalve valve when the tail is absent? What raised my suspicions on this specimen are the raised bumps on the external mold and the depressions on the cast. The pictures below are of the specimen. The first shows the cast/internal mold, and the second the external mold. It is from the Leighton Formation, Maine; which is Pridoli, Silurian. Thanks in advance for your help everyone! @Fossildude19 @mikeymig

    Platyceras sp.

    I have a nice little gastropod in my collection, from my most recent trip to the Leighton formation. I am pretty certain that this is a Platyceras sp, such as the one shown in the plate below, figures 23 - 24. Boucot, A. J., Yochelson, E. L. (1966) Paleozoic Gastropoda from the Moose River Synclinorium, Northern Maine. Geological Survey Professional Paper, 503(A). https://pubs.usgs.gov/pp/0503a/report.pdf I do not believe that specimens such as these have been assigned to species as of yet, and would greatly appreciate to hear any insight on their taxonomy. The lifestyle of these gastropods is pretty interesting. It is thought that they attached themselves to the anal plates of crinoids, to feed on their excrement. There is some debate, though, that instead this species was a suspension feeder, or was parasitic, boring holes in through the crinoid's shell. The picture below is of my specimen. The tip, unfortunately, broke off, but the rest of the specimen is intact, though it is laterally compressed. It is from the Leighton Formation, which is Pridoli, Silurian. Thanks for reading!

    Brachiopod id

    This is another fossil from the Silurian Leighton Fm, Maine. It is an excellently preserved internal and external mold of a brachiopod. It is similar to the Salopina species that I am constantly finding in this formation, but this brachiopod's valve is more strongly curved, instead of almost flat. It also has less numerous striae, and they almost reach the median process. As well as this, the dental plate is thinner and curves inward more strongly, and the ctenophoridium is wider. Any help on its identification would be greatly appreciated. Here are some pictures of it (internal mold on the left, external on the right):

    Salopina Brachiopod

    I have just finished preparing this nice pair of brachiopods. I am pretty certain that they are of the genus Salopina, but am not totally positive. The genus is marked as one of the most common brachiopods found in the Leighton Fm, as well as being considered a defining characteristic of this formation. Even though they are so common, I really never tire of them. The way these brachiopods were preserved, though, is rather interesting. @DPS Ammonite kindly acquainted me with the fact that these specimens are not internal molds, as I (pretty sillily) first thought. It seems that these brachiopods were preserved as an internal and external mold, and then the internal mold partly imprinted on the external. This would create a fossil that exhibited characteristics of both the internal and external mold. I unfortunately forgot to take a pre-prep photo of the specimens below. The photo was taken with the specimen wet, to provide more contrast. Thanks for reading!

    Algae or graptolite or what?

    I check this website from time to time and always learn something new. I am a bedrock geologist for many years - although I had a good training in paleontology, I still have to work hard to try to figure out a fossil. I recently and currently map rocks in northern Maine. The pictures show below are from a recently discovered greenbed basin (probably aged middle-late Early Devonian and deposited in a continental or sea-land transitional environment). My question is what are the dark-colored pieces? They don't look like burrows because they don't occur across layers. They don't look like tracks because they occur as separate pieces. They are not plant fossils. They appear like graptolites but I can hardly see any theca. Are they algae? Or what? Any help would be much appreciated.

    Anomalocarid ?

    I was packing up to call it a day searching crushed rock out by the old rail siding when I noticed this. Could it be ? The finds there are Ordovician I think.

    Tentaculites vs nautiloid id

    This is a another specimen from the Leighton Fm, Maine, Silurian. I uncovered it a while ago, and at first thought that it was a crinoid stem. On second look, though, I realized that the segments on the "stem" were curving inwards, instead of outwards. Furthermore, what I first that was the stem fading into the rock was actually the width and depth decreasing. I am torn between a Tentaculites sp., which is not known specifically from this formation but shows superficial resemblance to this specimen; and a small orthocone nautiloid, which is known from this formation. Any help on its id would be appreciated. Here are some pictures of it:

    Emsian mystery

    I took advantage of a cold day to sneak into the quarry. It's mud season and this road is one that has the potential to be a walk back from. I think it is most likely in the Emsian, Tomhegan formation. There is actually a fairly good representation of typical finds in the shot taken for scale. There appears to be a crinoid stem, or feeding arm near by, but what is the other shape/object ?

    Calymene trilobite ID

    These are more trilobite segments, and one cephalon, from the Leighton Formation, Maine, silurian. I believe them to be the new species of Calymene trilobite that I found earlier, but am unsure. The first pictures are of the first specimen, numbers 1 and 2 being of the cephalon, and the third of a thorax segment that was underneath the cephalon (you can see the edges of it in picture 2): The next pictures are of new specimens. Number one and two are of a cephalon. Unfortunately, I was unaware of its existence until after it came out in multiple pieces. It is about 1 cm by 1cm. Here are the pictures: Second are two different specimens. Number one is 11 mm by 5 mm, and number 2 is 6 mm by 3 mm. Here are the pictures: Any help would be appreciated. Thanks!
