is this even a (Cretaceous) fossil?
debivort posted a topic in Fossil IDIs this spatula-shaped item a fossil? Perhaps a coral or bryozoan? From a Cretaceous fossil cliff on the coast of Portugal. Matrix is limestone. Item apparently has two elements, 1) a flattened, darker "blade" that widens from end to the other, and 2) a lighter, roughly cylindrical element that runs down the middle. A mold of this cylindrical element seems to extend beyond where it ends.
Debbielebrecht posted a topic in Fossil IDI found this skull in our field next to our house last week. It was being pushed up from the ground. The photo shows the front R side of the face w/ clear jawline, R eye socket & R side of a crest. I would like ID help, please. We are 1/2 hour south of the WI border. It was near a fossilized, partially opened egg & the limestone-encrusted skull of a juvenile lizard, among other fossils. There are volcanic rocks nearby & we believe that the interstate Rock River was considerably larger, covering our property & bringing those things south to IL.
Limestone fossil from Bexar county Texas
hibou wu posted a topic in Fossil IDHi, this rock was found in a construction site in Bexar county, Texas. I think there are mostly mollusk shells, but I’m also really curious about the little tube things, which I’m guessing might be crinoids? Thank you for your help!
Doug Von Gausig posted a topic in Fossil IDI run across these guys frequently in the Mississippian Redwall Limestones around Arizona's Verde Valley. They are generally accompanied by lots of Crinoids and solitary Rugose Corals. They're always this oval shape with segmented structure. They look like an isopod, to me, but could be some other crustacean. Any help out there for the identification of these "bugs?"
Michigan brachiopod question
Bill Hoddson posted a topic in Fossil IDI have a piece of limestone found in a gravel pit. It contains two brachiopods I'm having a hard time identifying. Both appear to be the same species, just differing states of preservation. The larger is about 3/4" wide.
ID on find with (to me) unfamiliar texture
over9000bot posted a topic in Fossil IDFound close to Paderborn, Germany (Erwitte-Formation) alongside with some echinoids (most likely Micraster cortestudinarium),an ammonite and countless Inoceramidae clams. Marly Limestone Formation of the lower Coniacium or upper Turonium. I was wondering if it could be some kind of petrified drift wood, palm or root?
Are these fossils in a much bigger fossil?
Lone Hunter posted a topic in Fossil IDI ran across a pile of dumped limestone on a vacant lot in Grand prairie Texas, know nothing about it but I'm relying on the limestone experts on here for help. Most of it was shattered or blank but found one large slab about 4 ft across that was intact but cracked with some large peices left. I pried it apart and gathered up ones that looked interesting, had fossils, and large enough to maybe be distinguish as part of something else. Showing the group front and back for context. First four pics of one rock, next four pics of one rock and most interesting one, front and back of next rock, then
