Description
Two Fossils on the same block. One Enrolled and one Prone.
Here is your chance to own a classic piece of paleontology history from a classic site. A nice showy piece as well.
Classic Double Fossil Trilobite Flexicalymene from the famous Mt. Orab Shale Deposits of Ohio.
This is a Super Classic Double Fossil Trilobite block of Flexicalymene Trilobites. But these Ordovician Period fossils are becoming more rare as this quarry is beginning to play out. These trilobites are quite common in the Ordovician deposits near Cincinnati, Ohio. But the are normally found in an enrolled shape. They can be found while walking the riverbanks and stream beds.
Trilobites consist of a Head section with eyes, a body section and a tail section. The head and tail are normally solid shields. But the body section is made up of many body segments. Each segment has a pair of legs and gill branches.
The Super grouping of a Double Fossil Trilobite. Their method of rolling up is for protection from danger. And it is much like that of a rolly polly closing or just folding over. Because of this it can protect itself from danger and surviving.
During the Ordovician Period Ohio was the bottom of a shallow sea. Because of it’s location near the equator many large storms like hurricanes formed. But these storms did not only stay in the water. They hit the land and washed mud into the sea and buried many animals. Once buried the animals began the process of becoming fossils. Because the mud was fine grained the fossils preserved very well.
These two sit on a gray matrix that is 3 inches by inches.
