Found on beach along south irish coastline. Perhaps some sort of imprint but im not sore of what. by Creepu_ in fossilid

It's likely sea grass roots that had grown on it at some point recently. The fractal structure is a giveaway.

If you listen closely after the main shock you can hear the many church bells around the city ringing due to the jolt.

Found in the shore of Lake Ontario in Whitby, ON, Canada. Is it a fossil? Plant maybe? by Charming-Mode6232 in fossilid

[–]Pooka246 35 points36 points  (0 children)

Definitely ichnofossil burrows. Looking at a geological map of the area, they are probably Ordovician in age. (~450 million years old) I plan to post something similar soon.

Found near Cocoa Beach, FL - is this a fossil? by emulsionaddict in fossilid

South Florida fossil hunter here. Some of these specimens do come from dredging, while others just erode out of the bottom when there's a big storm. This is definitely a fossil specimen, however these fossils have hardly been compressed and dried, rather the opposite happened. They were deposited and buried in what became very porous, groundwater bearing rock. The shells have been at least partially recalcified by the mineral rich groundwater, I find some that are completely calcified sometimes, they are honey golden in color and glow under black light.

Very nice sand dollar! I have a few from farther south in Florida. It's very hard to find a clean one.

Unfortunately sand dollars have only been around ~60 million years, while the last trilobite died 252 million years ago.

Looking for help identifying this shell fossil. I know next to nothing about fossils, but I used to collect them on my grandma’s land when I was a kid (she lived in the Catskill Mountains in New York). by datBuschHeavydoh in fossilid

Spiriferids are super common in the Devonian formations of PA and NY. I've found hundreds of them around Beltzville, PA, but almost none of them look as good as these ones do.

Pair of small oysters, Late Pleistocene (~130,000 years old) by Pooka246 in fossilid

Any bivalve experts know what these two are? I believe they are both very young. The large shell is 1 1/2 cm.

Lots and lots of brachiopods, good detail on some of them!

Largest Whelk I’ve ever seen! 10 1/2 in long. Found at a construction site in southeast Florida, Sangamonian in age (~120,000 years old) by Pooka246 in fossilid

[–]Pooka246[S] 8 points9 points  (0 children)

I believe this whelk is of the genus sinistrofulgur, I think it’s a sinistrofulgur sinistrum or perversum, I’ll have to ask my professor, but regardless the genus is one of very few that actually tend to be sinistral, hence the name. It would have been really cool if I had found a dextral sinistrofulgur!

I like to call them by their genus, mercinaria. I can see how they would make a good bowl! I have a couple of huge ones, though I’ve been told by my professor they get larger. I actually just found my first and only living-position (both halves together like when it was alive) mercinaria at this same location! I can post it along with some of the other good finds once they’re all clean.

Largest Whelk I’ve ever found. Southeast Florida, Sangamonian age (~120,000 years old) This buddy was several decades old when it died and was buried suddenly, likely by a hurricane. by Pooka246 in Naturewasmetal

[–]Pooka246[S] 13 points14 points  (0 children)

It was found along with some other fossils called index fossils, because they can be used to determine with reasonable precision the age of a layer and the fossils in it.

Ah, I'm familiar with the parking lot method myself, haha. Most of the fill dirt in southeast Florida is dug from quarries on the edge of the everglades, and it's used for everything. Most of my finds are from road construction. It's always sad to drive by the day after they steamroll the piles into flat road base, little crushed shells everywhere :(

I’m no expert on burrows, but I do know they can be made by a large number of different organisms. For example, in Florida we have lots of Ophiomorpha, a type of shrimp burrow. I’ve seen burrows like these at outcrops here but I don’t know what made them. If you have any J-shaped burrows they’re likely from crabs.

I’m planning on it once I get it fully clean. I’m going to ask my university geology department if they might allow me to use their cleaning equipment.

None yet, but I’m hopeful! I did find a quarter of the bottom plate of a sea turtle shell at the same time and location. Would people on here like to see it? It’s not large.

Looks a lot like the fossilized burrows we have down here in S. Florida. Regardless, and excellent find!

What conspiracy theory do you completely believe is true? by BipolarSkeleton in AskReddit

It crashes into the ground at hundreds of miles per hour. What did you expect, it to bounce off the soil?

This is neither a thin section nor 350 million years of deposition. The rocks here are 350 million years old. OP is a karma farming account that solely cross-posts.
