Belemnite From NJ

Belemnitella - These rostrums are 1 to 2 inches long. They are tranlucent and lived about 100 million years ago from the Cretaceous Period. They were found in Big Brook, New Jersey. Belemnites are an extinct group of squid-like cephalopods. They had 10 arms but no tentacles. The arms were covered with small hooks instead of suckers like modern cephalopods. They lived during the Jurassic and Cretaceous Periods. Belemnites had no shells like earlier nautiloids. Instead they had an internal, hard, cone shaped structure called a rostrum or guard.
