[Geology2] Lake-bed trails tell ancient fish story

Lake-bed trails tell ancient fish story
PhysOrg.com [USA], May 6, 2010

The wavy lines and squiggles etched into a slab of limestone found near
Fossil Butte National Monument are prehistoric fish trails, made by
Notogoneus osculus as it fed along a lake bottom, says Emory
University paleontologist Anthony Martin. "This is a fish story, about
the one that got away 50 million years ago," Martin says. "And I can
tell you that the fish was 18-inches long, based on good
evidence." He led a detailed analysis, published May 5 in PLoS One, that
gives new insights into the behavior of the extinct N. osculus, and into
the ancient ecology of Wyoming's former Fossil Lake. "We've got a
snapshot of N. osculus interacting with the bottom of a lake
that disappeared millions of years ago," Martin says. "It's a fleeting
glimpse, but it's an important one."
