  4. The North Museum in Lancaster, PA, is a relatively small museum near me that's mostly aimed at kids but I enjoy still enjoy visiting. The exhibits are nice and I've seen a good variety over the years, though the limited space means that some exhibits don't always last too long. The whole museum was remodeled in 2014/2015 so there will be a discrepancy between some of the photos. I much prefer the older version I grew up with, since now the exhibits are a lot more generic-looking and less interesting in my opinion. A fossil Psaronius stump sits outside: Upon entering, visitors were greeted by some arctic animals: These were removed during the remodeling, leaving a rotating display case in its place, though more recently the wolves have been put back on exhibit on their own. Fortunately, the pteranodon above the lobby is still there, having gotten a repaint during the remodeling: There's also a case now with pteranodon fossils on the upper gallery overlooking the entryway: Now, for the old dinosaur hall: The T. rex skull was actually a new exhibit back in 2010 when it replaced a phacops trilobite cast and sculpture to join Tony McVey's T. rex. This moa is real. Pachyornis elephantopus, though billed as Dinornis. Several ostrich vertebrae were added to the neck before the correct number of vertebrae was known. This case was redone in 2011 from a dinosaur nest display to dinosaur skulls: There was also a hologram set up of a T. rex skull. I don't know why it's gone or where it went but it was rather unique. Unfortunately, the triceratops skull isn't on display anymore. I don't know its whereabouts but I'm assuming and hoping its still in the museum collections. This section of diplodocus vertebrae was donated to the North Museum by The Carnegie: The door in the upper photo once led into a blacklit room with all kinds of fluorescent minerals and other objects. It was really cool; I'm not sure why the museum did away with it. The wall was taken down and that corner is basically empty now. More recently, a fluorescent booth was added with some rocks inside, but it still doesn't compare to what they had. I took this photo before the skulls went out on exhibit. By chance I was in the downstairs gallery, saw the open door, and was invited into the prep room to see them: Now the dinosaur hall is on the other side of the building and looks like this: Interestingly, the tibia and fibula on the Camarasaurus leg are upside down. The signage even explains the mistake though I don't think there are plans to fix it anytime soon. The North Museum is home to the holotype of Sphodrosaurus pennsylvanicus. This megaloceros was on loan from the ANSP for a couple years. It was re-mounted for the Academy's 200th anniversary exhibit: There are also some cases with fossils which have migrated from the cabinet museum downstairs. Notice the lack of locality information on the signs; I'm not sure why they went without it but it would be more interesting for those unfamiliar to know where they came from. Skolithos linearis, probably from Chiques Rock in Columbia, PA. The room adjacent to the original dinosaur hall was mostly a Native American exhibit, though since it was more open this is also where the museum hosted traveling exhibits. The native American exhibit started with the origins of man, and traced the history of the local Susquehannock Indians through the different time periods. The North Museum has an impressive collection of local artifacts, but unfortunately the exhibit was taken down and the room was left mostly empty with some remnants of the exhibits that once passed through. This is one of the very few photos I've taken of the exhibit. The live animal room was once the first area you could visit from the entrance. It was since moved to the back of the museum. From the old live animal room: And the new one: On one of my visits, an upstairs room was open for quantum levitation demonstrations, and in one of the cases there were these old wood models: After the renovation some were in a case at the beginning of the exhibits but were removed so the space could be used to promote museum events. I think they may have been carved by H. Justin Roddy. He had a portrait painted in which he was holding the mastodon. This nautilus is in a case bordering the discovery room, mostly aimed at young kids with toys and some specimens they can handle. There are some other miscellaneous creatures in that case as well: The downstairs cabinet museum was left almost untouched by the renovation. Half the room has cases with birds and the other half is where most of the rock and mineral displays are. This case of exotic birds has been down in the stairwell for as long as I can remember. There are two of most species as well as a chipmunk. The birds were collected in Honduras and Guiana in 1892. This cabinet has some exotic birds but since it's in the corner the light isn't that great for photos. There's a wolverine down here as well: The North Museum's collections are old enough that a few extinct species are present. The mineral display begins with Pennsylvania minerals. The case starts with minerals found in Lancaster County on the left and moves on to those from farther away. \ Other minerals are organized by classification. There was also a fossil display, but much of it was moved upstairs into the cases in the new dinosaur hall. The fossils which remained downstairs disappeared recently in favor of a gemstone display. Acidaspis cincinattiensis from Swatara Gap, Lebanon County, PA Cryptolithus bellulus, also from Swatara Gap. Wanneria walcottana from Getz's Woods, Lancaster. I've visited the North Museum from time to time since I first went on a class trip there in second grade. It's nice to see the older style displays, especially in the cabinet museum downstairs. While it isn't as great as it used to be, it's certainly worth visiting if you're in the area. I'll try to update this post periodically since there's much more that I have photos of from my visits.
  5. I collected some crinoid columnals and a horn coral....weathered from the Devonian Keyser Formation limestone in Pennsylvania. As usual, preservation is not very good.

    Asteropygine fossil

    On December 4 my mom and I traveled to the well-known Seven Stars Quarry of Seven Stars, PA a second time (#1 in a post soon!), and our goal was to find more trilobites and cephalopods. This locality is Middle Devonian Mahantango Formation shale, full of a bounty of species. We had found many Dipleura and Greenops on our previous trip, as well as the cephalopods Michelinoceras and Bactrites. Many trilobites that I found were pyritized, the golden Greenops and red Dipleura. But surprisingly, Eldredgeops is absent from the site! Nearly every Mahantango locality includes Eldredgeops rana in the fauna! It seems that the larger and more powerful Dipleura outcompeted Eldredgeops in the large predatory trilobite niche. I wanted to learn more of why Dipleura is everywhere, so I picked through a 7-foot vertical shale hill on the hunt for more clues. I grabbed a large sheet of rock with well preserved Chonetes brachiopods on it and moved it into a bucket. Then I looked back at the spot where it was and sitting there was a small, nearly complete trilobite (above). I thought it was a Greenops at first. I wrapped it in some napkins from the Rutter's nearby, because two chunks were breaking off and it needed protection from further damage. When I got home, I got out my New York Devonian fossil guide (because it's helpful for many Hamilton Group fossil IDs such as Mahantango fossils) and searched for Greenops in the trilobite section. I observed the diagrams and descriptions, and after I checked my fossil for features, I determined that I had not a Greenops but a Bellacartwrightia. This is a rare species outside New York (mainly at Penn Dixie FP), which explains why I had only found one in my multiple trips to similar sites with fossils like Penn Dixie's. I was naturally excited. But as time progressed from Dec. 4 to today, I began to get suspicious of my highly thoughtless conclusion. I had no backup species to think about, if I had made a wrong ID. Today I was reading a paper on a group of phacopids and realized that a diagram of a pygidium on the paper was almost identical to my trilobite. I came to a much more acceptable conclusion: I had a species of Asteropygine trilobite. Annoyingly, I had no knowledge of what genus/species it is AND I had accidentally posted this cool bug as an entry for IPFOTM. I need to redo it. But, overall, a rare trilobite in Asteropyginae is awesome. What a trip!

    Are these crinoids?

    These three fossils in the upper left of the picture were found in central Pennsylvania. I am relatively new to the world of fossils so I'm hoping someone can help identify what I have found. Are these crinoids? Thanks in advance!

    SE Pennsylvania streambed find

    Hi everyone, I live in southeastern Pennsylvania in a small town just north of the Delaware/Pennsylvania border. I live on the edge of a large neighborhood next to a very old plot of woods with very large old growth trees. Next to my house is a stream that exits out of the neighborhood through a drainage pipe and into the woods. The streambed cuts down through into the ground about 6 feet below grade and when it rains heavy, the stream becomes a torrent of runoff that dredges up rocks making it an interesting place to walk after a storm. I've found many interesting rocks and even some petrified wood, most of which I believe is of the sandstone variety, but interesting none the less. About a year ago I found an interesting rock that I couldn't identify as anything specific but it was odd enough to place it up on the embankment on a wall of rock along with lots of other interesting finds I've made. It sat there for about 6 months, during which time the rain cleaned off the dirt and loose debris until one day I though this is really interesting and I brought it inside. I found this piece just down stream from a spot where a large pipe dumps storm water into the stream and cuts a large hole or pothole in the streambed and dredges up rocks from deeper below, maybe 3 to 4 feet deeper than the 6 feet below the floor of the woods. I'm not sure what to make of this but to my untrained eye, it looks very similar to bone structure that I've seen and also looks similar to other skull fragments discussed on this forum. I'd like to get some opinions as to what this might be. The location is about 2 miles north of Marcus Hook PA in Delaware County in a section of woods that as far as I can tell, has never been developed at lease not as far back as the 1800's when the entire area was farmland. During that time and now, these woods follow a stream that has been here for a long time undisturbed but surrounded by development. So here are some photos. If you needs any more photos or measurements please let me know. Thanks. Berwicker

    Fossil IDs in Burrow

    Hello everyone! This is my first post on the entire forum, I read the rules, the ruler thing doesn't work out too well since these are in a burrow - which I don't really want destroyed. I can try getting clearer images if anyone wants. Tried my best with these. Some people on another site mentioned one of these could be a worm in the Serpulidae family, another was mentioned as possibly being a barnacle. I live in Dayton, PA - this rock was found in a hill which was dug into for a pool few years ago. Have been looking around the area for interesting rocks and happened upon this, put it into a pile with other interesting rocks. Finally got around to brushing dirt off them and noticed the small white bits on this one. Any help would be appreciated !

    Beltzville State Park, PA

    Beltzville State Park is one of those rare parks where collecting is allowed. The adjacent federal land, owned and operated by the Corps of Engineers to operate the dam there, is accessible ONLY WITH A PERMIT. It is a functioning spillway and there is a gun range for the local police, so you and USACE need to make sure you are safe. With that important disclaimer out of the way, here's the good stuff! Beltzville is a very productive Middle Devonian site which includes the PA State Fossil, the trilobite Eldredgeops rana. Although no one in the group found any definite complete buggies, a lot of froglike trilo faces went home in our buckets! It wasn't all trilos, though. We found bryozoa, corals, pteria oysters, gastropods, crinoids and probably a dozen kinds of brachiopods. I led this trip for the Natural History Society of Maryland. The trip director made this lovely video of our day: https://www.youtube.com/watch?v=wdB5atWQmeQ Yes, I realized about 20 minutes after she took that video of me showing off the pop-outs that I was holding the fronts of the cephalons of one species, not the eyeballs of the other. This is what I get for not looking with my reading glasses first! Most of my finds I gave to whoever was sitting closest to me, but here are a few I kept.
  11. I got out again to gather a few small specimens of pet wood. Found in the Triassic of the Newark supergroup deposits in southeastern Pennsylvania.

    A few Mahantango finds

    I recently visited a few formations around PA, The Montour preserve pit happened to be on the way and I stopped by, The location was quite picked over as @historianmichael told me, but we did manage to get some nice finds. I will post a trip report later but for now, I want to get some IDs for some of my finds from here and another location. First, is what I thought in the field was a brachiopod but upon closer inspection, I realized that this is probably my first pteriomorph mollusk which is very exciting for me, my question is: Which? I looked through Linsley and multiple look similar, I just don't have enough experience with these to really be able to tell.
  13. Hello TFF friends! During the summer, in August I was able to take a trip to northwestern PA to collect some fossils at various locations. One of them had many different types of trace fossils which I did not collect (something I regret doing as those ichnofossils were quite interesting and beautiful), but I also found this piece, it is a thin sandstone piece containing multiple bivalve steinkern a from 1 to about 2.5cm in length. I am not sure what formation it was, the closest I can think of that is present in the area is Lock Haven but that one mostly has brachiopods and I didn't get a single one of those. I know these are bivalves because the shells have very similar form, some are paired just like two opened valves of a bivalve and two display growth lines along the shell, unfortunately those are very hard to see on camera. I was wondering if anyone knows what these might be as I have tried researching the topic myself but have gotten very few results. Thank you very much, Misha

    My Best Carboniferous Finds

    Hi all, I’ve posted a few topics on the forum but have yet to show my entire collection, or my best finds. So here goes. A little background on me. I’ve been fossil hunting since I was very young, probably since I was 4 when I found a plant fossil in my backyard. Over the past few years as I have ventured into adulthood I have gotten very interested in the fossils of the Pittsburgh area. I will display my best finds here and periodically update the thread with new finds. As a note, many of the vertebrate fossils I have found are rare and may be important to science. I have been in contact with @jdp about this and will most likely be donating the most important ones to the Carnegie Museum of Natural History. If any of my IDs seem strange or wrong please let me know, I am always learning and value new info. I guess I’ll start with the marine invertebrates. To start out we can start small, with brachiopods, cephalopods and horn corals. The first is a Linoproductus from the Ames Limestone, a classic Pittsburgh marine zone.

    Our Great I-80 Road Trip

    Greetings, all! After exploring outcrops and spoils piles from Quebec down to Florida, we are heading west from Delaware to Crawford, Nebraska and back this fall. Planning to stop by Sylvania, OH and Clear Lake, IA. Probably Richmond, IN. Any other suggestions? Thoughts on these three?
  16. I had the opportunity to collect plant fossils in Western Pennsylvania a few weeks ago. Success was had IDing the fern leaves. But I am having difficulty identifying the woody pieces found that are not Calamites. These came from the Glenshaw Formation, Mahoning Shale which is Pennsylvanian. I realize that a decaying swamp is full of twigs that likely are unidentifiable, but there seems to be structure in at least some of these which could lead to some sort of identification. I am hoping those knowledgeable with the Pennsylvanian flora can chime in. 1. Here are some larger pieces of plant material. Probably unidentifiable. Is the orange all plant with the centers structure being the piths or is the orange area staining and the only "wood" is the "pith" area? 2. Some smaller "twigs": 3. This one has evenly spaced projections which hopefully aid in identification. 4. This piece has some unique pattern to the wood: 5. Many circular items were exposed by spitting the shale. Would these be seeds or seed pods? 6. I like how busy and colorful this piece is. Is there anything identifiable? 7. Different types of plant material. Ideas? 8. This stem exhibits a pattern to it that may help with identification Thanks for looking!! I will try and post a trip report after improving my IDs!!!

    Fossil ID. Lehighton Pennsylvania

    Yesterday, after a very uneventful couple of hours of searching, I happened upon several fossils in close proximity right as I was about to call it a day. I believe four are horn coral, but would like confirmation, and would also like an ID on the other. One photo shows the four that were similar, and then a few angles of the one in the best condition. There is also one more I believe to be another type of coral. Thanks in advance!
  19. I found this in our backyard in a rock pile. I find many Devonian fossils in the shale lined creeks around Erie, PA. This rock appears to be similar but is extremely heavy and different colored. I can make out fossils but don’t recognize some of the imprints abs it appears folded and is SUPER heavy. For comparison, the rock I found with it, also pictured here is about 3-4x the size but the smaller one weighs 3x as much. No magnetism, but has a burnt spot. Was it perhaps originally a large piece of the lighter fossil plate that someone burned (possibly in a fire pit?) and that is how it appears metamorphic and significantly heavier or more dense? does not look like a meteor...no shiny smooth surface, etc.... any ideas?

  21. Hello again! I was wondering if anyone had suggestions for places in the north east US (around PA) that I could research? As was suggested to me, I’ve narrowed down the things I’d like to collect. I’m really interested in fossils that.. well look like things. Don’t get me wrong, shells and crinoids are exciting! But I’d be so jazzed to have fish, crustaceans, insects, or plants. Anomalocaris are so rad, though I fully understand that those are hard to find so I’m going to focus on other stuff for now lol. Maybe someday. My dad in particular wanted me to ask if anyone knew of any east coast places to find ants. I saw posts about an amber site in NJ but my understanding is that it’s pretty well picked through. He and I are going to the Montour pit next weekend to look for trilobites but I thought I’d ask for stuff he’s into. I’m going to be doing more research when I get home (I’m on mobile atm), but I’d love to pick your brains in the meantime! Thanks so much as always!

    Are these tracks??

    My husband purchased this landscaping rock in a pallet from a Bath/Bethlehem, PA area supplier about 20 years ago. Most of the supplier’s stones are from Pennsylvania. I’m guessing this is sandstone??? I’ve been staring at this rock for sometime and before I place it back, I wanted to get some opinions if anyone sees any type of tracks on this rock? I feel like my fingers fit in the specimen very nicely. Can’t tell if I’m seeing 3, 4 or 5 “toes” ? Maybe I’m just an imaginative newbie. Thanking anyone in advance who looks at these photos.

    McAdoo PA

    Found with the typical ferns found at McAdoo. Is this a seed (or spore) or just some kind of concretion?
