While exploring a cave in central Texas, scientists unearthed a long-lost ice-age ecosystem, including the remains of a giant tortoise and a lion-size armadillo relative, among a trove of fossils in an underground stream.
In a study published March 19 in the journal Quaternary Research, researchers say the cave may preserve the remains of animals that lived during a relatively warm period of the last ice age. If the findings are validated, the site would offer a rare look at an animal community that was missing from central Texas' fossil record.
