Day off work

[hemi123]

So, got off work early yesterday so decided to walk my open field area 25 miles inland off of the South Carolina coast. I have learned, and please correct if I am wrong, that this area is Oligocene formation or sediment layer. So spent around 1.5 hours walking and picking up lovely finds. Just wanted to share. Most of them are Angustiden, but a mix of a wishful Meg piece, and a few great white bits. I intend on leaving more from now on the pieces that are broken to leave for others to find. I think we can all tell from the laptop, which is a small 13 " monitor. Biggest one is around 2 inches, thats my beauty with the root, tip, and cusps.

What a great way to spend some time off!

Great finds!

Very nice!

Nice finds.

Can not be "great white" if the formation is oligocene. Great whites came out late miocene.

Thank you for the correction Ynot..........

That makes a lot of sense. I want to ask, is it possible for two or more formations to be present at one locality, either laying on top of one another or overlapping? Thanks.

Yes it is possible. You can have several formations exposed in a given area.

It is also known for older formations to erode fossils into a more recent deposit.

 

Maybe Someone closer to the area knows more about that exposure. @sixgill pete @MarcoSr @Boesse

Nice to hear that there aren't just ammonites lying on open fields That angustidens alone was worth the walk.

I've mostly collected the quarries and several rivers/streams further inland in SC, not open fields near the coast.  Depending exactly where in SC, I've found Eocene and/or Oligocene and/or Miocene (mostly reworked) teeth.  The teeth do look to be from the Oligocene to me, although some are too worn/damaged to tell for sure.  If Oligocene only, there wouldn't be any megs or great whites.  For that, the area would need some Miocene or Pliocene mixed in.

I am just learning the different stratospheres of sediment. But from the others that have posted here they have been mentioning what I had posted. In reference to what i find; I find a combination of meg frags, great whites, makos, angustiden, and hemipristis. So there IS a large variety, maybe as someone said above, the layers washed down into the creeks. I find them in the creek beds, not usually sticking out of the layer.

I really like the one in the bottom right corner

Sounds like You are working a "lag" deposit that has multiple ages in it.

Sometimes it is nice to find the mixed ages of fossils. You never know what will pop up.

 

Good luck.

In some areas, several formations can be seen at once.  It looks like you definitely have Isurus hastalis and possibly I. retroflexus in your finds.

So in the Charleston area, unless you pull a shark tooth right out of the Ashley Limestone, OR walk around at a construction site dug down into the Chandler Bridge Formation, every single shark tooth you will ever find here is pretty much guaranteed to be float or reworked. Most teeth are found in stream beds, and often when people go digging for big teeth they are really digging into the "Ashley Phosphate bed" - the basal phosphatic bone bed lag of the Pleistocene Wando Formation, which has reworked Oligocene, Miocene, and Pliocene fossils all mixed together (C. angustidens, C. chubutensis, C. megalodon, and Carcharodon carcharias teeth).

That helped a lot Bossee, thanks. Never thought of it that way. Guess thats why this past weekend I found one of the turtle shells(scutes?) of the old Galapagos turtles in the same area. Makes sense now.
