Ichnofossil Trilobite Snail Trilobite & Other Traces of Ancient Ecosystem 2511C

Has a few inches of trilobite track from several Trilobites but most of it is light (photo).

A snail feeding track round 4 inches that leads to another odd looking track down the edge (photo). 

And a few tiny worm tracks at the corner (photo).

A few more tiny worm tracks on the underside along with a couple partial impressions from a Sea Scorpion striking at prey (photos).

They are very light bit I thought worth mention.

Size 9 1/2 x 8 1/2 inch measured at the widest points

Weight just under 5lbs.

Fossils found near the Ohio River in Southern Indiana.

Found in natural state, we only washed the dirt off of them.

We think was from the Mississippian in age, from the Tar Springs Formation, over 300 million years old.
