Red Hill / Bray Creek Agate
« on: June 25, 2020, 09:38:42 AM »

I discovered this deposit back in 2010 near my now home in Payson. I took the local club there in March and these are pieces that came out of that trip.  It is a trace fossil and not petrified wood. It has been confirmed a long time ago. Dates to around 250-300 million years old.

It is indeed red! Can you explain what you mean by trace fossil. I'm not familiar with that term. Clearly you have been busy and contributing a lot to several activities.  The virus does provide a stimulus to stop and consider and expand what we do and how much time we actually have to do it.  Keep on keep'n on.

In this case, the trace fossil is the home of the creature that created it. A shrimp. You wont find any shrimp fossils in this material. Just the cast of its home that fossilized.

Hi Freeform:  I am looking but not seeing it.  Which specific feature in the rock texture is diagnostic of a shrimp home?  Thanks!

Hey Ryaly2dogs,  The entire piece is a cast of a shrimp home. They come in many sizes. These casts are whats left of a complex of holes and tunnels that where dug out by the shrimp.
