    ID help on two finds

    Hello, I have a few specimens my kids and I have found and need help identifying, if they are indeed fossils. I included a dime for size reference, but will try to include a measurement also for each: The first two images are a swirl shape in rock (I was hoping it was a shell) about 4 centimeters across The next images are of two round things (1.5 and 2 cm across) embedded in a rock, there are crinoid stems embedded near them All were found in Hamilton county Tennessee. Thank you for any info

    Cole Hill Invertebrates

    I went with the Delaware Valley Paleontological Society to a few spots in Central New York last month. Cole Hill Rd. in Hubbardsville has several outcrops on private land where the owners are willing to share with fossil hunters. We scrabbled up and down the scree - Whee- and found our fill of trilo-bits, including one Dipleura cephalon covered with druse calcite, plus oodles of brachiopods, nautiloids, straight-shelled cephalopods, gastropods of all different shapes, and bivalves. I learned a tough lesson that afternoon. Always wrap your specimens as you go. Not only will they keep from breaking, but they are easier to find when your bucket tips and tumbles down the hillside across countless tons of scree There were lots of pained faces around me as I hunted down the things I'd already found.. It took me half an hour to recover everything I could, but the best ones managed to make it home. Dilpeura trilobite cephalon Another trilobite cephalon, found by someone else in the group. This one is covered in sparkling calcite. Crinoid holdfast? with Ptomatis rudis gastropod unknown, probably nautiloid Cornellites fasculata bivalve Palaeozygopleura sp. misc. unknown brachiopods If anyone has any ideas, I'd like to hear them. This spine-shaped object is about 6 inches long. I'd discount it as variations in the rock color, but the left end is curved outward from the matrix. Worm trace fossil. They made carpets of these on the sea floor.

    Roadcut in Hamilton

    Today I decided to go and visit a roadcut that I red on one of the Silurian literatures I got my hands on (a big thank you to those that led me to those PDFs relating to the geology of the Niagara Escarpment). It turns out the roadcut on the Niagara Escarpment is near my home which is a pleasant suprise to me, considering that I have been disappointed by the Queenston formation. This roadcut is actually several exposures that run on an access road that can lead one to the upper part of Hamilton, Ontario. Here is the exposure I decided to explore. I chose this exposure as the access is a busy boulevard with cars driving by with no sidewalks and pedestrians. I had several people honk and call out to me as I was exploring the site. Maybe I should have worn a safety vest of some sort? Is that even necessary?
  4. With the 3 day weekend, I was finally able to get out for a fossil hunt! I was located mostly around Utica NY. Day 1: I started at the bottom of the ocean with a benthic Triarthus site near Little Falls. After some literally prickly encounters getting down to the river, I pulled the thorns out of myself and had a beautiful little spot! Naturally the in-tact shale was on the opposite bank, so I had a nice cool wade on a hot summers day and thoroughly soaked my boots. The voyage was well worthwhile I’ve never worked with shale this clean before. One piece was 3x3 feet, and with the slightest tap, you could flip through the “pages” like an enormous stone book. to start us off here are some photos of the site and some finds. Help with ID on the algae/sponges accompanying the Triarthus trilo-bits is much appreciated! Any tips on prepping these Triarthus too? The shale is thin and they seem to be mostly upside down.

    Leaf-like Fossil

    Hello, I found this object a many years ago. It was the first fossil that I remember finding. The rock in my area (Hamilton, NJ) is mostly from the Jurassic and Cretaceous, but there is a small section of Cambrian rock and a lot of glacial deposits. I found it on a path in a park, so it could have been brought there by the park managers. It looks like a leaf to me but I could be wrong. It also has a small indent at the bottom. I hope that you can identify it. Thank you in advance.

    Community on the Half-Shell

    I love finding multiple fossils. I don't just mean multiple specimens in a single rock, I mean fossils that show evidence of more than one life-form. Shells with burrow traces, for one example. Dung beetle balls. Predation marks. And particularly, epibionts. Here I have a fairly ordinary specimen of the brachiopod Tropidoleptus carinatus. Ordinary, that is, until a closer look is taken.... This specimen supported an variety of other critters on its pedicle valve. Whether the epibionts took hold while the brachiopod was alive, or colonized the dead shell, I don't know; I would speculate the former, as the brachiopod is articulated. I think it is likely that the whole living community was buried together by mud. So who's here? Let's take a closer look. We have several examples of Cornulites hamiltoniae. Some are (relatively) large, while others are very small: Two more Cornulites pictures, then we'll see who else lived here!

    Devonian Cephalopod

    I found this yesterday in Avoca, New York. It's about 3 cm long. The core looks like a cephalopod of some kind, but the exterior has me puzzled. If it were soft tissue, it wouldn't have preserved, but I have found impressions of a few others like this there and in another site over an hour away. The one field guide I have shows nothing like it and I may have to go hunt down the original 19th century sources. Any clues?
  8. After going around in Hamilton, Ontario looking for a river/creek to check out the iconic Niagara Escarpment of the city, I decided to check out the Devil’s Punch Bowl which is located in Stoney Creek, Hamilton. Most of the waterfalls located in the old city of Hamilton are out of reach/barricaded/no-go zones with fines for trespassing because of safety reasons. Nearby Albion Falls and other waterfalls like Tiffany and Chedoke in the old city of Hamilton cannot be explored close up because of the tourists and locals that have died and severely injured themselves from falling while on the cascading waterfall. Today I was surprised to realize that the bottom of the Devil’s Punch Bowl was unbarricaded and so off I went to explore it. It seems the only place that tourists and people go to when visiting the Devil’s Punch Bowl is the observation deck at the top of the falls which offers a nice view of the falls. This is evident as I noticed that there was barely any trash at the bottom of the gorge and down river. The height of this falls is 37 metres. Today the fall is dry with no water. Theres a large Timmy’s cup on the bottom right for size comparison (it isn’t mine though!). There are various formation in this rock exposure of the falls and assigning loose rocks from the ground to the right formation can be a hassle.

    Anomaly from Penn Dixie

    Came across something interesting today while excavating the Bay View Coral bed at the site. First thought was a hypostome from a Dipleura dekayi. It is not. There are symmetrical sutures in it, which are pretty interesting. Wondering if anyone has some literature on Devonian fishes from the Hamilton. The only thing I can think of is placoderm. It's about 1mm thick and 4-5cm across. Sorry for the poor photo, I took it in situ with my phone.
