The dinosaur of the day: Brachylophosaurus
- Hadrosaurid that lived within the Cretaceous in what’s now Montana, US, and Alberta, Canada (discovered skeletons and bonebeds within the Judith River Formation and the Oldman Formation)
- Identify means “short-crested lizard”
- Described in 1953 by Charles Mortram Sternberg, based mostly on a cranium and partial skeleton
- Sternberg discovered the fossils in 1936 in Alberta, and at first thought they have been Gryposaurus
- Kind species is Brachylophosaurus canadensis
- Species named refers to the truth that it was present in Canada
- Later, it was discovered {that a} partial cranium found in 1922 may very well be referred to Brachylophosaurus canadensis
- In 1988 Jack Horner described a second species, Brachylophosaurus goodwini (named in honor of collector and preparator Mark Goodwin), discovered within the Judith River Formation (although in 2005 Albert Prieto-Márquez mentioned the variations between the 2 species have been both due to particular person variation or the results of the second species specimen being reconstructred with an the other way up cranium crest
- Extra specimens have since been present in each Alberta and Montana (although extra have been have been present in Montana now, particularly since a bonebed was discovered close to Malta, Montana, and has over 800 specimens)
- About 30 ft (9 m) lengthy as an grownup, although Gregory Paul estimated it to be 36 ft (11 m) lengthy and weighing 7 tons
- Had a comparatively small head, lengthy decrease arms, and a large higher jaw beak, lined in a sheath
- Had cheeks to maintain meals in and dental batteries, and frequently changed tooth
- Head was elongated (vast on the rear and slender alongside a lot of the snout)
- Had massive nostrils
- Had a bony crest, which was flat and paddle-like excessive of the again of its head, and had a ridge on the midline (additionally, was not hole)
- Crests various, relying on age (some lined a lot of the cranium, others have been shorter and narrower)
- Might have had sexual dimorphism, the place males had bigger crests than females for show
- Crest might have been used for pushing contests for show (not sufficient proof to know for positive)
- Delicate tissues have been present in Brachylophosaurus “mummies” (tissue changed by minerals, so it’s the fossil of a mummy)
- Most well-known “mummy” is nicknamed “Leonardo”. Leonardo is 90% lined in tender tissue, and reveals that the bottom of the neck had a variety of muscle, that there have been small polygonal scales on the broad beak, there was a midline frill on the again made by triangular-shaped projections, and that the second, third, and fourth fingers on its arms have been in a tender tissue so it appeared like a mitten
- Leonardo was discovered within the bonebed in 2000, by Dan Stephenson
- Leonardo obtained his title as a result of graffiti close to the place it was discovered mentioned “Leonard Webb and Geneva Jordan, 1917”
- Leonardo was a juvenile when it died, and was 22 ft (7 m) lengthy and weighed between 1.5 and a couple of tons
- Leonardo had pebbly pores and skin texture
- Leonardo’s intestine contents have been preserved: ferns, confiers, magnolias, and pollen from greater than 40 completely different vegetation
- Leonardo additionally had small, needle-like worm parasites in its abdomen (different dinosaurs might have additionally had parasites)
- Lived in a moist enivornment, and mummification normally occurs in dry circumstances, so not clear the way it was mummified (tender tissues might have been preserved one other approach earlier than the physique decomposed)
- In 1994 in Malta, Montana, Nate Murphy discovered a whole, nicely preserved Brachylophosaurus that he nicknamed “Elvis”
- Different specimens discovered embrace “Roberta,” (virtually full), “Peanut” (juvenile with pores and skin impressions), and “Marco”
- Peanut is on show on the Judith River Dinosaur Institute in Malta, Montana
- Proof of tumors have been present in Brachylophosaurus skeletons in a 2003 examine
- Tumors could also be an indication of inbreeding (not sufficient genetic variety, results in the rise of tumors)
- Different dinosaurs that lived in the identical time and place embrace the ceratopsian Chasmosaurus, the hadrosaur Parasaurolophus, the tyrannosaurs Daspletosaurus and Gorgosaurus, and the troodont Troodon
Enjoyable Reality:
Sir Richard Owen named Dinosauria, however the three animals he based mostly the group on have been all named by Gideon Mantell. Owen additionally thought Dinosaurs have been associated to pachyderms (a doubtful title for elephants, rhinos & hippos).
