Fun stuff - Yorktown Formation - pliocene?

Recommended Posts

Your fossils are quite beautiful! I remember taking a trip when I was much younger to a phosphate pit in Florida. There were shells very similar to yours littering the ground, and mixed in with them were shark and crocodile teeth and a whole host of miscellaneous bones. It was perhaps one of my favorite fossil trips I've been on. My expertise does not lie anywhere near the vicinity of the Pliocine, but do be on the lookout for vertebrate material!

 

Thanks for sharing!

I like crinoids......

Love the fossils. Tell me about how you have them displayed. I have been tinkering with some artificial water and fossils with the intent of putting a display together for a local park this winter.

Yeah, nice. Looks like what we find here in Florida, and some of the species are likely the same.

The folks that live on the property put the fossils everywhere... All over the inside of the house and their garden. The lady there has started making little turtle sculptures out of oyster shells. lol

 

The ones I've collected I haven't done anything with so far. I found one shark tooth and I'm hoping to find more though. If anyone can identify anything they see in my pictures (click the link to see the full album), please let me know!

Cool material!  Definitely Zone 2 Yorktown either Rushmere or Moorhouse Member.

Nice Finds VirginiaWilderness! Looks similar to stuff from down here...

 

Hey Mike, so I keep seeing Yorktown references and the similarities to the Sarasota material and wanted to ask if this chart is still pretty current with respect to Yorktown and Tamiami ages? I suspect you may have mentioned it one of your blogs/refs and should have read it but I just accidentally stumbled across it and started to read about the big picture in the Pliocene again....If I could just remember 0.01% of what Ive read or someone has told me to read I might be worth a dang...

It is fairly accurate although some paleontologists might have different views on the ages of some of the units.  For instance, where to place the Caloosahatchee equivalent James City and Wacamaw Formations in this chart.  I would need to go back and read the paper but I am assuming that only part of the Caloosahatchee is in the Gelasian with the remainder along with Wacamaw and JC in the Calabrian and Bermont Formation in the Middle Pleistocene.  The main change is that the Pliocene boundary was placed a couple of years ago to 2.58 mya putting those units in the Gelasian as Lower Pleistocene.  Here is a link to the latest ICS chart LINK.

Those are some amazing finds!!! I really like pectens... 

And is that a Busycon on the trunk completely to the right?

Thanks Mike! I wasnt even aware of that of that chart...I think I've always used the GSA's version. I've been out of the loop I guess for years...thanks again.  Regards, Chris

Thanks Chris for sharing that paper.  I thought it might have been a publication that I referenced before but it is not and is relatively recent (2009).  It is a nice review of the US and English Pliocene.
