Three undergraduate students from the University of Arkansas made a world-class discovery this week when they uncovered a 325-million-year-old nautiloid fossil just yards from two of Fayetteville's busiest roads. At exactly eight feet in length, their find represents the longest actinoceratoid nautiloid fossil in the world.
The specimen uncovered by Kee, Morgan and Gillip represents what Manger calls a pathological giant. Its discovery lends credence to a theory that Manger first proposed to the scientific community in 1999 -- that these nautiloids exhibited semalparous reproductive behavior. Like modern-day squid, these creatures would have mated and laid eggs within three to four years and then died.

iterparous species - mate many times, repeated reproduction
semelparous species - mate once/lifetime, big bang reproduction
