A New Fossil Species of Armored Fish
In 370 million-year-old red sandstone deposits in a highway roadcut, scientists have discovered a new species of armored fish in north central Pennsylvania. Studying and describing this fish’s anatomy, they took advantage of a technique that may look like it was stolen from crime scene investigators. Dr. Ted Daeschler, an associate professor at Drexel University and vice president of the Academy of Natural Sciences of Drexel University, describes this method using a rubber cast and fine powder to better show the edges of plates and fine ridges on the fish’s bony armor.
