I have a rock feature that I am a bit doubtful, but hopeful about. I have a few "crystalized" fossils and have seen some very nice ones from near my hunting area also posted. This does mean that there are some out there. This little feature measures almost 11mm long and is 6mm wide. In hand, the left side really looks like a head segment of some sort with the line and what does look like two eye spots. The main area has what looks like segment end features going around the sides. The square crystal feature in the center is a totally new one for me. I have found literally hundreds, if no

Diplograptus amplexicaulis Graptolite & Cryptolithoides ulrichi Trilobite on matrix SITE LOCATION: Viola Limestone, Murray County, Oklahoma, USA TIME PERIOD: Ordovician Period (445-485 Million Years ago) Data: Diplograptus was a Cambrian genus of graptolites. Graptolithina is a class of hemichordate animal, the members of which are known as graptolites. Graptolites are colonial animals known chiefly as fossils from the Middle Cambrian (Series 3, Stage 5) through the Lower Carboniferous (Mississippian). The name graptolite comes from -
Partial fossil, maybe gastropod, cephlapod, chiton - too far gone to tell?
turtlefoot posted a topic in Fossil ID
Hey All, I don't know if there is even enough of a fossil here to identify. I am nowhere near good enough to give a real good guess. First thought was either a small piece of a cephlapod or chiton. If it is a gastropod, it is a type that I have never found before. It was found on the side of a dry creek bed near Willow Springs, Missouri, USA in an Ordovician Formation. The remnant that remains measures 13mm wide by 15mm long. The bed the fossil remnant is laying is measures 24mm long. There is an indented type of division going horizontally across the fossil. It does not go -
Working on my own id's. Is this a Hyolith, Gastropod, Rugose Coral or something else?
turtlefoot posted a topic in Fossil ID
Once again, I am studying and working on my own identifications. I am just needing someone to either confirm or correct me on this one. My first guess when I saw it was it was a gastropod of some sort, but after researching and looking at images online, my guess is that it is an internal cast of a hyolith. It was found in northwest Howell County, Missouri, USA. The fossil in question measures approximately 16mm and the host rock measures 80mm across. The widest point across of the cavity where the fossil in question lies is 8mm. Once again, I am truly appreciative of any help that you ar -
First point, I cannot get a decent image of this fossil to save my life. That being said, I took a bunch of sub par image in hopes someone can put the pieces together to come up with an id. It measures approximately 35x22mm and is definitely a different material than the host rock. I found it in the same area that I have been finding all of my other fossils. This is outside Willow Springs, Missouri, USA. I originally thought it might be a rugose coral of some sort, but it looks to have horizontal segments or something similar. I am about 95% (or more) positive that it is a fossil and not

Hi All, Why am I not finding any trilobites (or even any identifiable trilobite partials)? I know the obvious two answers would be that I am either overlooking them or I am hunting in an area that they will not be located in. I am hunting outside of Willow Springs, Missouri, USA in what I believe to be Ordovician Period rock. I am finding all sorts of crinoid, brachiopod, gastropod, bryozoa, rugose, favistella fossils and more. I have even found a large stromatolite reef but I cannot find a trilobite fossil. I would think with the diversity of the fossils that I am finding, tr

micro organisms encased in clear glass-like "rock"
BILL GROMMES posted a topic in Micro-paleontology
We have a fist-sized glass-like object that contains 22 microscopic organisms from the Cambrian and Ordovician periods. We theorize that it was produced by a meteor impacting sand and water resulting in perfectly preserved organisms, some of which also have soft tissue preserved. We do not have equipment to investigate this object any further and are seeking someone to help validate this finding. Does anyone have knowledge of a clear glass "rock" with encapsulated 500 mya organisms ever being found? -

Geocoma corinata Brittle Star Anti-Atlas Mountains, Morocco Ordovician Period (485.4-443.8 million years ago) Geocoma is an extinct genus of brittle stars that lived in the Jurassic. These are slow-moving low-level epifaunal detritivore-suspension feeders. Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to 60 cm (24 in) in length on the largest specimens. They are also known as se -

Order Orthida brachiopod Pennsylvania, USA Ordovician Period (485.4 -443.8 million years ago) Orthida is an extinct order of brachiopods which appeared during the Early Cambrian period and became very diverse by the Ordovician, living in shallow-shelf seas. Orthids are the oldest member of the subphylum Rhynchonelliformea, and is the order from which all other brachiopods of this group stem. Physically they are usually strophic, with well-developed interareas. They also commonly have radiating ribs, sulcus, and fold structures. Typically one valve, often the brachial valve, is flatter -
