I don't even know which direction to go, geological or biological, and given the weird concretions and burrows in Eagle Ford don't know where this fits in so looking forward to answer

Hi, I'd be grateful for a ID on this fossil, found today at Worbarrow Bay on the Isle of Purbeck, UK. I can't see anything similar online but my best guess would be coral. Would be very grateful for any deeper insight!

Hey all! Throughout my many years collecting from around the Cotswolds, there has always been one constant: these weird, tubular structures. Originally, I thought them to be corals, when I was much younger. More recently, I have IDd them as the ichnofossils of a Serpulidae. If anyone could confirm or disregard this ID, I would be very thankful!

After my move to Florida, as I unpacked my fossils, I came across this. Any ideas? Possibly giant bacterium or microscopic, cigar-shaped alien space craft? Algae? They are ~3mm long. Salona Formation. Trenton Group Middle Ordovician Antes Gap, PA Tom

Hey there! This is my first post on The Fossil Forum. I don't have a lot of knowledge about fossils, but I sure do know how to find them. Hopefully these aren't too obvious and boring, but I'm incredibly curious anyway. I found these near Sheep Bridge north of Phoenix, Arizona. Here the Verde river has cut through deep layers of ancient lava, sandstone, mudstone, etc. I was exploring for crystals up on a steep hill along the river's canyon walls when I came across a whole lot of these things. They are very fragile and I didn't want to break apart some of the 2-3 foot wide boulders of them so as to preserve them for others to find. Anyway, my understanding is that this area was once a sea floor, so I'm assuming they are some type of coral, anemone or something similar. The fossils are composed mostly of the same sediment which encases them, so I suppose they must be trace fossils, but please correct me if I am wrong. Other not-so-filled-in ones even had crystals and other minerals lining the cavity. As well, I looked at a geological map of Arizona and the area I was exploring is composed of the following... Late to Middle Miocene Basaltic Rocks (8-16 Ma): Mostly dark, mesa-forming basalt deposited as lava flows. Pliocene to Middle Miocene Deposits (2-16 Ma): Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. There are a couple photos of some ball shaped objects which were very easy to knock apart from the surrounding stone. I have no idea what those could be. The rest of the photos are of the coral looking objects. Some of them, if still intact, were nearly 24 inches long, but I left those behind and only took smaller samples. Please note how the "head" of the corals appears to flare out and is larger than the rest of the stem. Finally, some of them appear to have a little node sticking out of the "head," but I suspect that may be due to weathering as these are very fragile fossils. Thank you all so much for your interest and help and I look forward to learning more!
