The dinosaur of the day: Lophorhothon

• • Hadrosauroid that lived in the Cretaceous in what is now Alabama, U.S.
  • Name means “crested nose”
  • Type species is Lophorhothon aptopus
  • Species name means “uncommon” or “strange”
  • First dinosaur of its kind found in Alabama
  • Discovered by Rainier Zangerl, Bill Turnbull, and Charles Barber while on a Field Museum expedition, in 1946 in the Mooreville Chalk Formation (near Selma, Alabama)
  • Holotype includes a fragmented skull, vertebrae, and parts of the forelimbs and hindlimbs
  • Holotype was probably washed out to sea by a river, and then sank and was buried
  • Holotype is now in the Field Museum of Chicago’s collections
  • Named in 1960 by Wann Langston
  • Herbivorous
  • Estimated to be 14’9 (4.5 m) long
  • Since the holotype, has also been found in the Black Creek Formation in North Carolina
  • Some scientists think it may not be a valid genus (might be a juvenile Prosaurolophus, or, as James Lamb suggested in 1998, it may be a basal iguanodont)
  • Others, such as Horner, Weishampel, and Forster, in 2004, said it was a basal hadrosaurine
  • A 2010 study found it was a basal member of hadrosauroidea

Fun Fact:

A large portion of this came from SV-POW

Argentinosaurus probably pooped about 400Kg (900lbs) per day.

If it was all excreted at once, the pile would be about 1/4 the size of the larger pile shown in Jurassic Park.
