Brad Behr, 14, son of Mr. and Mrs. Earl R. Behr of Tamaqua, found an unusual and valuable fossil specimen wich experts say is over 300 million years old. He and his two younger brothers found it in an outcropping of rock known as the Stroudsburg Cut while on a family field trip. Unable to identify the fossil, they took it to the Academy of Natural Science in Philadelphia. There it was identified as the shell of an orthoceras, an ancient animal ancestor of the moder squid, which lived in the Devorian age.
