  • Had a collection of passages the place air flowed by way of from the snout, into the crest, and right into a maintain above its eyes
  • Unclear what the fan-shaped crest was for, however might be to draw mates
  • These complicated nasal passages might in all probability make sounds
  • Appears to have extra fast development of its nasal than different equally sized dinosaurs
  • Like most juvenile hadrosaurs, Velafrons has a proportionately giant cranium, however for its growth stage (juvenile/sub-adult) the cranium continues to be fairly giant
  • Sort and solely species is Velafrons coahuilensis
  • Genus title means “sailed brow”
  • Genus title refers back to the sail-like crest on its head (additionally described as hatchet-like)

  • Discovered a partial juvenile skeleton and principally full cranium
  • Cranium and skeleton have been disarticulated
  • Took two weeks to dig out the cranium (out of 12 toes of rock and soil)
  • Took two years to arrange the cranium, and it was ready by Jerry Golden, a volunteer on the Utah Museum of Pure Historical past
  • Similar to juvenile Corythosaurus and Hypacrosaurus
  • Though a juvenile, discovered distinct sufficient to be its personal genus
  • In 1981 William Morris described ?Lambeosaurus laticaudus (with a query mark in entrance as a result of it was not definitive, since no full crest was discovered), primarily based on a partial cranium present in Baja California, within the El Gallo Formation.

  • One of many first dinosaurs named from Mexico
  • When it was named, it was the primary new North American lambeosaurine named in over 70 years
  • On the time Velafrons lived, there was a heat, shallow sea from the Arctic Ocean to the Gulf of Mexico, and Velafrons lived on Laramidia, on the southern tip (what’s now Mexico)
  • Lived in a moist estuary, the place rivers meet the ocean
  • A number of fossilized snails and marine clams have been discovered within the space, so it lived close to the shore
  • Different dinosaurs that lived across the identical time and place included giant tyrannosaurs, troodontids, ornithomimids, and ceratopsids
  • A number of giant storms, which appear to have result in many mass deaths (giant bonebeds of jumbled hadrosaur and ceratopsian skeletons discovered within the space)
  • There’s a sculpture type of Velafrons, as Ichiro the Dino, 30 ft skeleton constructed for Burning Man by Marianela Fuentes, and after went to Washington D.C., and was on an eleventh ground roof deck for some time. Had colourful bones impressed by the designs of the Huichol tribe in Mexico
  • Ichiro moved on to the Kids’s Discovery Museum in San Jose, CA final February
