Just a quickie

Found these two today whilst knocking around some dirt. Not sure if they are fossil or not. Down here we have a lot of shells and a lot of "reworked" dirt and sand,so to speak. Which means I'm not sure if they originated where I found them or if they were moved there by construction and/or backfill.

Any input is welcome.

Nice shells. @MikeR will know for sure.

 

 

Cheers.

First looks like Bursidae (Bufonaria ?).

 

Second one perhaps Turritellidae.

Maybe Marsupina bufo and Turritella acropora?  Possible recent but maybe Middle Pleistocene Bermont Formation.  Regardless, the frog shell is a nice find.

Thanks for the help. The majority of my finds are modern animals and shells but sometimes it's hard for me to tell. What I look for is enamel? If it still has some enamel usually file it under extant. No enamel goes to the fossil box for possible ID. 

 

Here's a massive horse conch I found recently. It's about 18 inches long. Looks fossil but not.

Only teeth have enamel. The shells are made of a different material, Nacre.

That looks like our Florida Horse Conch now Triplofusus papillosus (formerly Pleuroploca gigantea, a name I liked much better). These things can reach 2 feet long!

 

 

Cheers.

@ynot my apologies, I thought nacre was mother of pearl and not present in our Florida conchs, thought they were considered porcellaneous hence why I used the term 'enamel'. But then again I really have no idea what I'm talking about anyhow.

 

@digit Yep it is Triplofusus papillosus, it was a awesome find for me. I don't see the really big conchs often around here.

Here's another lucky strike.

A Queen Helmut Conch. It's 9 inches long and as big around as a dinner plate.

You are correct about this, I used the wrong word (can't think of the right one[ calcium carbonate]). But it is not enamel either way.
