Imprints of The Past

College student David Fillmore made a wild discovery two years ago. He found full-body imprints of three ancient amphibians. Researchers had collected the 330-million-year-old imprints decades earlier but never looked at them closely.

The imprints are of foot-long Temnospondyli (tem-no-spon-dul-eye). Scientists say they lived long before dinosaurs.

This discovery is exciting because imprints reveal so much information. "They show what the texture of the skin was like," said Spencer G. Lucas of the New Mexico Museum of Natural History and Science.
