Scientists have found an exquisitely preserved skull of a herbivorous dinosaur species in New Mexico, known for its weird head adornment.
The skull belongs to the iconic tube-crested dinosaur Parasaurolophus, which lived during the Late Cretaceous period, about 76.5 million to 73 million years ago.
Parasaurolophus were herbivorous reptiles that sported trumpet-like nasal passages which they blew air into through the so-called tube on their head.
This particular skull belonged to one particular species of the Parasaurolophus genus – Parasaurolophus cyrtocristatus.
The newly-revealed specimen would have been roughly 20 feet long (6.1 meters) and around 7.5 feet tall at the hip (2.3 metres) in its day.
Despite its extreme morphology, details of the specimen show that the crest is formed much like the crests of other, related duckbilled dinosaurs.
The first new skull discovered in nearly a century from a rare species of the iconic, tube-crested dinosaur Parasaurolophus was announced today in the journal PeerJ. The exquisite preservation of the skull, especially the bizarre tube-shaped nasal passage, finally revealed the structure of the crest after decades of disagreement.

Jan. 25 (UPI) It s been almost a century since paleontologists last unearthed a skull belonging to the tube-crested dinosaur
Parasaurolophus.
But thanks to a newly excavated fossil, scientists have gained fresh insights into the evolutionary origins of the species unusual tube-shaped nasal passage.

Originally recovered from the badlands of northwestern New Mexico in 2017, the newly analyzed skull described Monday in the journal PeerJ suggests the crests of Parasaurolophus dinosaurs formed much the same as those of other crested species, such as duckbilled dinosaurs.
Two men stabbed during altercation at gas station
SOUTH BEND, Ind. Two men suffered stab wounds following an altercation at a Phillips 66 gas station on Michigan Street on December 13. A suspect has been charged in the case.
When South Bend Police arrived to the scene, they found one man with a stab wound to his abdomen and another man with stab wounds to his left knee, side and buttocks, reports said.
