Fossils on a Pedestal


Recommended Posts

There is a small road cut exposure I like to frequent in the Plattsburg fm. where the Hickory Creek shale is excavated at a relatively shallow angle.

The whole formation it extremely fossiliferous, but specimens with great preservation require diligent and persistent searching.

But, to the subject of this post, an interesting means of finding those great fossils is in timing a good rain with a day or two of drying and wind erosion.

The shale is very loose and it seems that what happens is fossils (and of course 'just rocks') of certain weights and sizes hold their ground while the shale erodes away underneath them.

I've affectionately, though probably not originally, coined them as being pedestaled.

Here are a few recent examples:

 

Orodus(?), Cladodont fragment, and Horn Coral

Thank you, guys!

@fossilized6s I've been lurking! The membership knowledge base and specimens are rapidly exceeding my limited input. That's a good thing!:D

It's always cool to see fossils perched like that.  I see that here in Texas at the Waco Pit.  I just love it.  Makes it easy to find.

That is awesome! I wish my Paleozoic teeth were that easy to extract!

Nice. The corals at Hungry Hollow erode out like that as well as the pyritized ammonites on the clay hills of the Provence in France.

:DI just recently found these 'easy pickings'. Up until then all of the ones I found were locked in the hard limestones.

As hard as they are to find I'll take 'em however I can get 'em!

It's cool to see others have this luxury, also.

I've also found tiny pyritized goniatites in this shale.

Neat photos-thanks for sharing them. I like the way the finds present themselves. Sometimes it makes it easier for us older folks who are crawling on our knees to make things out. I was terrorizing an old curled leaf the other day by mistake...but I did find a pedestaled tapir tooth. LOL. 

Regards, Chris

Ha! Yeah, I spent 5 minutes photograping a petalodus crown in situ before I figured out it was a spider shedding  'cocoon'!:(

I can't recall the number of mesquite beans I've picked up thinking they are something fossilized.
