Trilobites At Oak Springs

Good afternoon folks.  DesertDale is on the go again.  Our site at Chief Mountain is magnificent.  We even that a thunder storm and rain.
My "Sweet Man" took me on a ride to see the "Trilobites" at Oak Springs Summit. 
Where there is even an area OHV for riders, but not as nice as Chief Moutain OHV Area.

Trilobites are a fossil of  a animal that lived in the sea, some 10 million years ago.  Evidence shows that warm, well-oxygenated  waters in the world's oceans were disrupted and replace by the cold water, from thw ocean depths.  Many of the animals could not adapt to the change.
When the trilobite died , the parts of the shell often became separated.  Most commonly you will fine just the head thoracic segments and tail.
At Oak Springs there are 6 types are found in the tan-colored shale, as DesertDale is doing here.

Common fossils may be collected from public lands for personal use in reasobable amount.  They can not be bartered or sold.
