Dug up in Maryland.

Both of these possibly came from the Galveston TX area, they were found in a box with other Texas items. Both are heavy. And one shell has other fossil like pieces attached to it. These were inherited from a deceased relative so I don’t have much info on them. Both have pinkish blue insides. Any help is appreciated!

Here I begin on this journey of identification! Thank you all for the kind welcomes! After looking through some of the resources on this site, I've come to wonder if this might be a Crustacean of some kind. This comes from my great-grandfather's collection, collected somewhere along the coast of South America in the 1940's. There is a dried (animal?) inside. All photos where taken in natural light.

Actually I cleaned the shell and removed inner matrix. I got this while digging at beach .

Hello everyone, I found this conch in N. Cape Coral, FL. They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm. Can someone help me verify and identify this fossil? Is it Strombus floridanus? Thank you!

Dug this up near the shoreline at Caspersen Beach. Looks much older than any other specimens I have found in the area along the beach, which also tend to have much more color. The defined lines and ornate features certainly stood out to me the first time I saw it. Too bad it isn't in great condition, as the original shell could have been over 8" long/tall. Haven't looked online to research it yet, so I figured I would ask on here for some expert opinions!

These washed out after a rain from a line along a hillside in southeast Missouri.

I grabbed this shell today because I thought it was absolutely beautiful. Plus I heard these shells are getting rarer and rarer. I know it's not a fossil, but would anyone be able to possibly give me an ID? The length is 8 inches.

By the title your probably skeptical about me actually finding a fossil in my backyard of course I didn't actually find a real fossil in my backyard as that would be quite fictional. I thought I would say that before beginning the fossil ID help... Because in reality I found 2 fossils in my backyard not one!!! In the lot beside my house is dense forest I live in Florida with very invertebrate rich soil in fact almost all soil in my area (suburbs near Indian river) contains hundreds of small shells Pleistocene to recent. However last year when I was looking for modern animal bones I was very surprised to see a white shard sticking up from the ground I tried the porous test with my finger but it was not positive so I concluded it was most likely not bone as most Pleistocene epoch fossils are much more reactive to the test than older fossils and since in my area there are only Pleistocene to recent fossils I assumed it was an invertebrate so I started to excavate the area. To my surprise I found a very large conch-like shell I actually had to cut the roots of a nearby tree as the roots were going through the shell. I later came back and found yet another specimen. It's quite the story to find literal fossils in your backyard but anyways here are the two specimens i'm curious to see your opinion on them please feel free to ask for different pictures and or questions. Thanks in advance, -RJD Yellow>First Specimen Orange>Second Specimen Blue>Modern Invertebrate IF YOU ARE TRYING TO ANSWER ID USE COLOR CODES PLEASE AND THANK YOU,

When my wife and I visited Jeff's magical "Cookiecutter Creek" to stock up on some micro-matrix to sort through while the Peace River reloads the gravel beds throughout the summer months, we found a number of bivalve and gastropod shells in this marine fossil deposit. Many of the shells were rather beat up but a few of the bivalves were complete (with a matching set of valves) and a few of the gastropods were acceptably intact enough to collect. The most interesting one we found were a few intact conch shells. From some online image searches I believe this may be (or be related to) Melongena corona, the Florida Crown Conch. The most distinctive and eye-catching aspect of this species is the row of sharp protuberances not only around the upper shoulder of the whorl but also along a second row closer to the anterior canal (opposite the apex). The examples I found seem similar to the shells of the extant Crown Conch but from what I seem to see online the protuberances on the shoulder seem to point more upward toward the apex (forming a bit more of a "crown" in appearance) where on the fossils these points are directed much more outward. Anybody on the forum familiar with the fossil gastropods commonly found in the southwest portion of Florida who would be willing to confirm or suggest a better ID for these intriguing little gastropods?
