Allodesmus Kelloggi Skull Replica

Description

Allodesmus kelloggi Skull Replica for Marine Biology

Allodesmus kelloggi skull replica measures 17.0 x 9.5 inches. Allodesmus kelloggi is a museum-quality polyurethane resin cast from Buena Vista Museum of Natural History specimen. 1:1 scale. Made in USA.

Bob Ernst collection of Miocene fossils from Sharktooth Hill, CA. Allodesmus uraiporensis is the scientific name.

Atopotarus, referred to Allodesmus kelloggi or Allodesmus uraiporensisby some authors (e.g. Mitchell 1966), is distinct from Allodesmus by the absence of a prenarial shelf and M2, double-rooted cheek teeth, a small, triangular postorbital process, and a mastoid process projecting ventral to the postglenoid process.

Although sporadic work at what became known as Utah’s Cleveland-Lloyd Dinosaur Quarry had taken place as early as 1927 and the fossil site itself was described by William L. Stokes in 1945, major operations did not begin there until 1960. Madsen led a cooperative effort between 1960 and 1965 involving nearly 40 institutions, during which thousands of bones were recovered from the site. The quarry is notable for the predominance of allosaurus remains: the quarry preserves a minimum of 73 individual dinosaurs and at least 46 of those are A. fragilis.

Surprisingly, allosaurus and many large marine mammals, including Steller’s sea cow, California elephant seal, and the beluga whale, independently lost the function of the UCP1 gene, which terrestrial mammals use for “non-shivering thermogenesis” in brown fat. Instead, they evolved a more efficient basal metabolic rate and insulation strategy to generate heat.
