250 million years ago
pretty much everything died.

Long before the dinosaurs we
know from school and Hollywood
stamped around eating cavemen
armed with Clovis point spears.

[Ook. Unconformity – the very essence]

There were lots of really
beautiful reefs then – full of
happy aquatic life: trilobites;
ammonites the size of truck
wheels; all sorts of pretty
bivalves and sea lillies.

Now they haunt the Guadalupe
Mountains and rattlesnakes
and lizards sun themselves
on the dry reefs of West Texas.
