Meiolania, an extinct cryptodiran turtle that ranged from the Oligocene until nearly 2000 years ago! We just missed it! Damn!

A rad Pareiasaur from the AMNH. Who needs diapsids when you can have awesome anapsids, anyway?

Sandy, laterally accreting channelform incised into floodplain/shoreline coals in the Cretaceous Book Cliffs of Utah; this famous outcrop is right on I-70, and has probably been responsible for a number of insurance claims among geologists, I reckon!

A rad Ophiomorpha in some turbiditic sandstones from the Book Cliffs, Utah. This trace fossil is a burrow made by a shrimp, held together with fecal pellets plastered to the wall in order to stabilize the structure in noncohesive, shifting sand. The bumpy, rugose texture of the trace is a result of the little fecal pellets. NEAT, HUH!?

Trace fossils on deltaic sandstone bedding surface, from the Cretaceous of the Western Interior, Book Cliffs, Utah.

What do we want!

FISK!

When do we want it!

NOW!

Okay, here it is...Fisk (1944), Plate 22-6.

Pennsylvanian aeolian cross-strata exposed along the Alcova Reservoir, Wyoming. Big honkin' cross-bedding, for sure!

Western Interior Seaway Carbonates and Shales, exposed, shockingly, in flat-as-a-pancake Kansas. See? Even boring flat places have SOME interesting carbonates!
