    What did i find?

    During a recent (Sept.16) fossil hunting adventure I was searching for the source of the concretions containing fossil ammonites to get a better understanding of the stratigraphy I was standing in. So I went to the top of the slope/cuesta to check out the current highest layer. It was tons of saltine cracker sized bits of shale/sandstone and slabs of the same protruding out of of the lip of the ledge. No fossils were visually evident so I pulled the nearest slab out and flipped it over. The slab was smooth on the top and when flipped had a loose coating of either white calcite or shaly bits like smashed potato chips/crisps on it. Brushing the chips off revealed what you see in the images. The period is Cretaceous and possibly Triassic. The fossil concretions had the appearance of a massive mortality...like the Ordovician extinction event. Any ideas, suggestions or correct ID of what I found and absentmindedly left behind at the end of my adventure? A closeup from the left corner of the above. My first thoughts were this is some kind of marine forest of sponges, corals, plants, with other fossils mixed in. Or trace fossils like burrowing animal trails or maybe crinoids. I'm stumped having never seen this and a big dose of rookie-itis. What say you? BTW- pay no attention to the rock on the card..it was just a paperweight to keep the wind from blowing the card away.

    Baculite Mesa - WIPS Trip 2023

    Well, this year we did not battle the gods of snow and mud. The temperatures were also not scorching this year, with a nice breeze and a hint of a drizzle coming into the area instead. This Baculite Mesa location is always a (WIPS) Western Interior Palentological Society favorite led by our respected leader Malcolm Bedell. Several experts on the site were in attendance, so good advice and information was graciously provided as always ... Looking toward the mesa. The helpers are READY ! .. they did a good job this time. The hike there and back took a good three hours of time. Exercising their little muscles for a dad win. Only have a few of those so they are treasured. Comon' dad, I wanna climb ! Ok, first, we must stop off and smell the flowers blooming in the desert this time of year. This is the typical presentation of the Baculites, usually as casts. Or eroding quickly out of the formation. We have had tons of rain and snow this year, so their scattered skeletons were everywhere. Generally I pick up a few as giveaways. Still some of the original shell on this one. A good example of what you will usually find in the area. I was most interested in exploring the Tepee Buttes this year. These carbonate deposits were created by cold methane seeps. These seeps, in turn, colonized by microbes that fix the chemical energy, supporting a vibrant marine community. There are at least half-a-dozen surrounding the local area. Inoceramus sp. are common at the vent sites. I believe these bivalves are Nymphalucina occidentalis and are common on the buttes. They often are filled with calcite crystals. A bit of Inoceramus sp. shell You can also find traces of the baculites in these formations as well. The climbing was the best part for the kids. Several of the baculite fossils found that day had these large round concretions attached. Our local resident expert indicated that these concretions hid crab predation marks. Large predation entry points created when the crab popped open the shell like a tin can, to feed on the baculites, as they came to rest on the sea floor. The second site was better this year. My daughter was the first to flip what she thought was a stone. Low and behold ! ... a male ammonite fossil. Dad found the female. Lying in a wash, an arroyo, at the second collection location. A few more finds .. nothing to write home about, but they will be great for schools and to give away to those future fossil hunters. Cheers, Brett
  4. Hello all, I got the chance recently to dig a small patch of the Severn Formation of Maryland for original shell Cretaceous fossils. It was a two day project and I worked for hours both days to extract as many fossils as I could (knowing this may be my only opportunity there) and go through all the layer I could access. In the end, I think it was worth the effort! I ended up with two Discoscaphites, a partial Sphenodiscus, baculite, and a good amount of bivalves I have to get labeled. Here are my finds from the weekend.
  5. Hello everyone! I wanted to share the project that I'm most proud of this year. Over the last year, we've been poking around, trying to find formation in a Merchantville stream in Central New Jersey. We had to dig (a lot) for this but found a few diggable areas. This is a sensitive spot as it's the only place in the world you can find Menabites walnutensis (besides a few isolated examples from Texas), and it's the only place in the USA you can find Baculites vaalsensis. There are a lot of other goodies too so I'll show my entire collection from this area. My favorite Menabites walnutensis...
  6. I was able to get out for the first mountain hike this season recently after being held back due to storms. The weather had been too hot the last several weeks to get out in the mountains due to afternoon thunderstorms building up making it hazardous for hiking and to leave an aircraft exposed at 5,000’ elevation. Most of the large pictured ammonites are Pachydiscus sp. so here we go, a photo trip in the Matanuska Formation, Member 3. Yes, it is as steep as it looks. Not for the faint of heart. This particular ammonite has been exposed for three seasons now and too steep to get a closer view. One of my old friends:) A new ammonite from the spring snow melt erosion. This concretion has 4 ammonites present in it. Another “Old Friend”, each season gets a little most erosion around it and subsequent exposures. The suture pattern and description matches Pachydiscus kamishakensis. Where there is one often will be more in close proximity. Pelecypods are present in great abundance but most are fragmented. One of the few pelecypods mostly intact. Another old friend, 26” peleycpod. I have posted pictures of the giant clam previously. I’m going clam digging tomorrow and one like this would do for a years worth of chowder. I have been mainly focused on looking at ammonites and taking my time on this trip started noticing other fossils. This is a piece of a baculite imbedded in a concretion. Once I noticed this one I saw more similar smaller baculite fragments. The backseat passenger looking at an area where belamites occur. The alpine flowers were out in full bloom. Back to the Red and White magic carpet ride to fly home.

    Baculite from Pierre Shale

    I got this baculite in a fossil show. From the Pierre shale of South Dakota. He gave me a handwritten label that I can't tell what it says 100% Regards - Adriano
  8. Our local geological society does a small but very nice "Earth Treasures Show" about this time every year. While most of what I picked up were more in the line of mineral specimens, I did score one fossil this year. Nothing spectacular, I realize, but better than anything I've collected on my own. Nice sutures. Incidentally, I just got volunteered to be our program director, which means I'm in charge of finding an interesting speaker every month. With COVID, we've been meeting by Internet the last few months, which has actually expanded our scope for speakers not from our area. If any of y'all know of a paleontology or geology speaker who gives a great talk, who might be interested in doing an online for us, I'd be much obliged. We usually have a pretty appreciative audience -- both professional and amateur earth scientists, many from Los Alamos National Laboratories, though we're a hobbyist club rather than a professional society.

    North Sulphur River Trip

    Pictures from my latest NSR trip. Some mosasaur verts and bones, a jaw, ammonites, baculites, and of course the normal array of oddities. No really good verts but still fun. Does anyone know what jaw this would have come from? Also the turtle looking shell and the large white bone next to it feel a lot heavier than recent bone to me so maybe Pleistocene. Ill send a few close ups of those and of the crazier stuff later.
  10. Finds from North Sulfur River in Ladonia Texas. Baculite part of a nautilus. Baculite Bits of Baculite All the layers of a huge gryphea On left 2 huge gryphea. Red and black baculite. the algea covered thin over TX I thought could be the underside of a sea urchin. Sorry a few rocks snuck in there and at the top at first I thought it was a chunk of petrified wood but now am thinking it could be a wore down bone fragment.

    NSR Hunt 3/15/2021

    Went for a short hunt at the NSR today, with only a few finds - it's been a minute since there's been a good rain, and it seemed well-picked-over where I was looking. I found a few pieces of bone, including a couple of either finger bones or very small vertebrae. I also found a piece of flint with potential microflaking. Perhaps the best find is a potential large scraper tool. Bones in situ: I think this could be a scraper based on its general shape, material (chert), and the nature of the flaking - which only appears on one edge: Though, I am certainly not familiar with artifacts, so I welcome more experienced eyes.

    North Sulphur River Vert

    I took a trip to nsr after some decent rain in the middle of January. Here in Texas the weather can be hot, cold, or anything in between and it turned out it was a nice day in the 60s. I found a decent mosasaur vert, some decent ammonites, and a few other items. Let me know what you think. Pictures 4 and 5 where of a huge ammonite. You can tell by the rock pick it was over a foot wide and the picture doesn't show but the outer shell that was deteriorating was iridescent and really pretty. I don't think I have seen an ammonite with actual shell still intact however everything else was pretty much eroded. I also provided some in situ shots of the verts. Also pictures 28 and 29 are of a really worn piece of bone that had one side covered in matrix or was possibly fused with another type of rock? Anyone know what items: 8 and 9, 10 and 11 are? Also I haven't done any research yet but it appears there are several different types of ammonites I found. Picture 27 are those burrows? If so any idea what creature made them? Lastly item 6 and 7 appear to be cow teeth. I'm assuming they are modern? 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
  13. I found this in 1989 on the upper Powder River in Wyoming. It was in an area with lots of these baculite-shaped things. I thought it would make a great knife handle so that's what I did. However, I've never seen anything like it. It has the general shape of a baculite but the exterior seems to be covered by something. I get the "sense" of a type of sea weed, or a jelly fish or something, but I doubt very seriously something soft like that could fossilize. So I am looking for an expert to tell me what I have. Also interesting, is different aspects of the "raised" features are different colors. If you can enlarge these pictures, you might be able to see the roundish darker thing. Thanks in advance for any input.

    Wyoming Baculite Identification Help

    Hello, Last week, I found this baculite eroding out of a concretion in Casper, WY along the recreational bike path. The shale erodes out of the hillside and is presumably part of the Cretaceous Cody Fm. Can someone help me verify and identify this baculite? Are there any references to the stratigraphy and or fossil assemblages in the Casper area? Sorry for the poor photo quality. Thank you!
  15. Found this on the surface in a Brazos River feeder creek near Houston. It was not near any known exposure, but the Brazos itself transport marine Eocene and Paleocene from up north. It also erodes out Pleistocene bone pretty often. The bank of this feeder creek was sandy with clay underneath. One end of the cross section appears to show something organic within. When looking in from the empty end, the cavity wall is rough but doesn't look like bone-porous. Lick test of the outer surface is positive, noticeably, which makes me think this is marine. Overall, the segment is 1" in (outer) diameter and 1" long. I am still novice at fossil hunting, but this is entirely unfamiliar to me. I would guess baculite or horn coral, but only the because of the shape Any ideas appreciated!!!

    Plesiosaur Bones?

    I suspect this to be mosasaur. Can anyone confirm and more accurately identify?

    Help on Sea Fossils

    A customer gave me some neat fossils today, I couldn’t tell ya where they were collected unfortunately. Is the larger one a baculite? No clue on the smaller one. Larger one has crystals inside the fossil, pretty neat. Thanks in advance.

    Baculite with "Nautiloid dinner"

    Good morning folks. I have a strange Baculite that "appears" to have eaten a Nautiloid for it's last meal. I dropped the Baculite and it broke. Originally I was disappointed until I saw the contents. The Baculite is from Belfush, Dakota. Am I wrong or does the Baculite seem to have ingested a small Nautiloid?

    North Sulfur River Hunt

    I completely forgot that this last weekend was a "holiday" weekend and went on a day tripper up to the North Sulfur River near Dallas (an almost 5 hour drive). I met a new fossil friend named John who was going to take me to some of the more 'out of the way" spots he usually hunts to try to find a few specific things - a mosasaur tooth and vert being the top of my list, plus he was going to take me to a spot where we could hopefully find a really awesome looking cephalopod (Scaphites). The first spot was already picked over, sadly, the disadvantage of not getting there before 10am I guess! I found a few nice baculites (which I love and was happy to find including a cool red one) and some other nice little things, gastropods and such. Then I thought I had found something awesome....a nice little bone stuck in the gravel. WHoo hoo!! Was it a mosasaur??? Something Pleistocene? A GLYPTODON???? I was so excited!! Until I got home and looked it up and .....it's a cow astralagus. Yay. Not even a bison. Meh. (I think, anyways...I did look it up and saw some previous FF posts about the difference between Bos and Bison and pretty sure mine is just a Bos). So a question....was Bos around in the Pleistocene? This isn't 'modern" bone, I think it is at least partially mineralized. But I really don't know. So, as relatively disappointing as that was, I still came home with some GREAT stuff- a couple of nice shark teeth (a new one I had not found before, even if it was John who picked it up...I WOULD have found it if he wasn't ahead of me....but he was nice and gave it to me. hahahha) AND even though we busted open a bunch of phosphate nodules with no luck at finding the Scaphites I was looking for.....he had an extra one to give me. SO I came home with lots of fossil gifts! My "consolation prize" - Trachyscaphyties . 3 inches diameter . My first Goblin Shark Tooth : Scapanorhynchus 2 inches Baculites - love the suture pattern Two chunks of a red one (not sure if they were from the same one, but they sort of fit together!) A different Baculites - not sure of species, but it doesn't have the same suture patterns and has more surface detail. maybe just not as worn down? The Atralagus bone: And this i THINK is mosasur bone, but very worn down. 2 inches A cute little Inoceramus clam 1 inch and lastly, some Exogyra ponderosas. Hopefully I can make it out there a few more times before they dam the river and maybe find that danged Mosasaur tooth and vert.
