Most likely the museum referred to here is the Natural History Museum in Exposition Park.
The creature may have been part of the bird hall exhibit on the second floor. Maybe he's the bony guy on the right.
Gus Arriola started his brief animation career as an inbetweener at the Charles Mintz studio. He moved over to MGM in 1937, where he became an assistant animator and, finally, a story sketch artist, primarily in Rudy Ising's unit.
Arriola left MGM in 1941 after selling his comic strip Gordoto United Features. He was drafted in 1942 and found himself back with Ising in the First Motion Picture Unit at Fort Roach. Gordo went on hiatus on October 28, 1942 ("Remember that the only one to blame for unpleasant changes these days ees that dorty jork - Heetler!!) and returned as a Sunday half-page in May of '43. The daily strip returned in 1946 and ran until 1985. According to the World Encyclopedia of Comics, Gordo "became one of the most widely published and read strips in the country."
An interview with Arriola from Hogan's Alley can be found here.
Below are some of Arriola's model sheets of the bad guy from Hugh Harman's The Lonesome Stranger, followed by some early sketches of Gordo that used the bad guy as a point of departure. These drawings are from the book Accidental Ambassador Gordo by Robert C. Harvey and Gus Arriola. Go buy it.
Los Angeles Memorial Coliseum, in the '30s.
USC and the Coliseum. Photo is undated, but seems to be from the '20s or '30s.
The game was USC vs. Berkeley, and ended in a tie.
An undated photo, apparently taken by Carmen Maxwell and pilfered from Bill Hanna's book, of the MGM cartoon studio.
The studio was located at the northeast corner of MGM's Lot 2, at Overland and Montana Avenues. The building is long gone, as is Montana Ave. for that matter (it's now called Palm Court Way.) Lot 2 is now the location of the Culver City Senior Center and a housing development with streets named after some MGM stars. See it from space here.
