My epic collection

Organisms displayed on Triassic moenkopi ripple formation siltstone. Some older, some younger. The triassic period lasted between the "Great dying" Permian-Triassic extinction event roughly 251.4 million years ago to the Triassic_Jurassic extinction event 199.6mya (wikipedia).

The moenkopi formation is aged at about 240my.

Fossilized snail shell next to the broken calm shell was found at carpenteria beach and is of unknown age.
