While hiking through a desert area just southwest of Tucson, AZ. I found these interesting layered rocks. Over the course of an afternoon I came across a couple more spots where these types rocks were strewn over relatively large areas. Many of the pieces would fit inside a square inch or the palm of your hand, while many others were a few feet long/wide. I showed these to a local geologist and he called them stromatolithic Paleozoic limestone – evidence the area was once covered by water and these represent the layers of algae, probably in the form of algal matting that existed there, dating back to the Paleozoic time period. Respectfully, can anyone confirm or negate this idea? Thank you for your time and consideration!

We split open this rock yesterday and it has a mirror image of two things I am not sure of. #1 I see some shell... #2 Vegetation?

Today I am up loading a favourite fossil oof mine, I like it because of the calcite quartz geode in what appears to be a brachiopod shell. I live on the Niagara Escarpment. At one time the area was sitting just below the Paleozoicequator, tilted at a more 45 degree angle, in a more east/west direction than the land sits now. This explains the weird road angles to me now, probably formed when the terrain dictated the road directions, but I digress. The Niagara escarpment in Ontario starts at the Niagara Falls, follows along the Lake Ontario Shore, through the cities of St. Catherines, Hamilton, and Dundas, where it takes a sharp turn north in the town of Milton, toward Georgian Bay. It follows along the shoreline of Georgian Bay through Collingwood (The Blue Mountains) across over to Owen Sound, along the shoreline of the west side (where I live) over to the town of Wiarton, up the Bruce Peninsula and carry’s on from there. Having written all that, I need to mention the Ojibwa an Anishinaabe people are the indigenous peoples here, who live with us. I have observed with many of the fossils I find are worn as if the waters were quite turbulent, probably from the heavy tidal action during this time. The moon was much closer to the earth some 430 million years ago, our days were approximately 19 hours long as the earth was spinning faster, and the moon was also spinning. The gravitational forces must have been unbelievable! (Dynamic, biological and anthropology concequences of lunar and angular radii, Steven A Balbus, published 08 August 2014. These are my thoughts today, please let me know what you think.

Hello everyone, I working in dimension stone field in Armenia. This fossils where found in a sample small stone block brought for cutting to the factory, then they were machined polished as standard marble or granite tile. The tile (second photo) is 400x800mm app.16x32 inch. Kindly help me to identify these guys. Thanks

TRILOBITES - These appear real...
leelee51 posted a topic in Is It Real? How to Recognize Fossil Fabrications
What's your take --- are these real? Considering purchase. Details: "Selenopeltis buchii trilobites", 45 x 35 cm (total size), Paleozoic, Upper Ordovician, discovered in Morocco.

I picked this up in the sugarloaf area of the snowy range. The French Slate is in the area but this is much lighter than the outcrops I’ve seen were much darker, kind of bluish in color. It’s pretty hard. Doesn’t seem to want to cleave but is foliated. So, slate? Phyllite?

Hi everyone, just joined the group. I recently did a kayak trip down the Brazos River Below Possum Kingdom Lake and found some petrified wood. I was wondering if anyone knew of what geologic age and formation it might be from? The surrounding geology seems to be Paleozoic but there is also Pleistocene terraces. Is it possible the wood could have been mineralized in a Pleistocene terrace or is this more likely from a surrounding Paleozoic formation? Thanks in advance for the help.

Its from a Paleozoic massif, i think maybe it is a quartzite with plagioclase feldspar bands. What do you think ?

In the diagram of the cross-section of the Wealden Dome in SE England (https://commons.wikimedia.org/wiki/File:KentGeologyWealdenDomeSimple.svg), Paleozoic rocks exists beneath the Wealden Supergroup, but no age of the Paleozoic rocks is given in the diagram. What is the precise age of Paleozoic sediments underlying Cretaceous rocks in the Wealden Basin?

This silvery gray crown of a fossil Crinoid is quite impressive for its vascular arrangement of arms and protruding aboral cup. However, it is the nature of its preservation that makes this piece very special. The fossil is pyritized as the metallic mineral Pyrite replaced the organic matter during mineralization.

This is roughly 2 1/2 inch in length. At its widest point 1 1/2 in and a 1/4 in thick. Any help identifying it would be much appreciated

Here is a limestone reef rock from Tucki Mountain in Death Valley. The strata is vertical. There was a band of reef rock several hundred feet across. Lots of crinoids but it's the sponge / archaeocyathan fossils that I'd like to know about. This is the first time I've done this, so I'm not sure how the answers arrive... Thanks very much! Dick

Here are some color pencil sketches of some Paleozoic agnathans I drew many years ago (maybe 6 or 7 years ago). Time is scarce, but seeing these again I somehow feel inclined to start sketching some new concepts again Polybranchiaspis yunannensis (Galeaspida) Early Devonian Qujing, Yunnan, China Haikouella lanceolata (Agnatha, Haikouellidae) Early Cambrian Chengjiang, Yunnan, China Stensiopelta pustulosa (Cephalaspida) Early Devonian Ternopil, Ukraine Pteraspis (Pteraspiformes) Early Devonian Ternopil, Ukraine

Hey guys, So I discovered there is actually GO transit service from Hamilton, Ontario to Brantford, Ontario and Im actually excited to discover this (HOORAY!!). Does anyone know the geology of the city? Im also looking for papers/files that can help me know what to find there. Thanks for any help!

I just went to this traveling exhibit in a museum in a city where my brother lives that it is about the animals and life in the Permian period and I got pictures of 3 fossils, an ammonite, a trilobite and a crinoid but I don’t know what species and genus they are?

I visited a small Paleozoic (Silurian) coral reef in Indiana the other day. No earth-shattering, jaw-dropping discoveries, but it's an interesting spot with dolomitized fossils. Here's a google earth view of the center of the reef. A nice mollusk, if anyone knows what species, let me know. It shattered when I tried to extract it, but I was able to glue it back together as you can see here. Sphaerexochus romingeri cephalon After extraction.. I believe this is a Platyceras: To be continued..

Hey, I like finding really any fossil but the Devonian is especially my favorite & while I'm at it I need some identification on a fossil. I absolutely know that it is not a Mollusca shell or brachiopod shell. So that's me!

Hey guys do any of you know where I can find Some placoderms here in Black Hawk County Iowa? I have only found a plate piece here and some of my friends found some WHOLE PLACODERMS. while I only have one tiny plate. If you can help me please and thank you!

Hello, I'm 12 years old and my name is Kenan S. I think I have found a new species inside a Tabulate Coral! There seems to be tiny bivalves inside of the coral after I split the coral in half. Wherever the growths are there is a cavity in the coral missing from the region. Also something new to my notes on this coral is that it grows hexagons (like any Tabulate coral) but over each other, but when the 'parasite' eats at the coral it does not grow over the spot or just makes a couple new polyps like any other coral (I own a couple living corals in my 75 gal) it kills the surrounding couple polyps, and creates a new area of polyps. I put this find under this category because of how small the parasitic creatures are. I can barely see them with my own eyes and my microscope is currently broken so that's that.

Can anyone identify the possible location where these might have been picked up? These are some of the last remaining unidentified and un-located items that I acquired from the old rockhound couple in Nanaimo, that caused me to come to TFF for ID help in the first place. I'm only getting around to it now. These aren't the most spectacular or important fossils, but it's always worth it if you can attach some info to them. Otherwise I'll eventually toss them out for garden rockery, probably. I thought I saw some similar items that someone had posted not too long ago, from a river in Ontario, in a town that started with P - Pickering? But I never followed up on it and I can't find that topic now. I suspect these are all from the same area, whatever area that is. They're all Paleozoic marine, and all but #3 are water-worn. First: This first piece I have already posted but I never got any confident answers about it. Maybe combined with the others I'll get further with it.
