Jack McIntosh (1923-2015) + giant plesiosaur from Argentina + more news
Some recent news and blog items:
McIntosh, John Stanton: January 6, 1923– December , 2015.
McIntosh received his Ph.D. in physics from Yale University in 1952.
His interest in dinosaurs began as a child, but when in college he was
told to get a degree in a “real” field in order to get a job. McIntosh
might have become the successor to Barnum Brown at the American Museum
of Natural History if he had stayed in paleontology. No matter;
instead he became the world’s leading authority on sauropods, and his
classification was the standard for more than 20 years. He was also
instrumental in putting the right head on Apatosaurus in 1979.

Interview with Jack McIntosh
Maybe his most famous paper, correcting the skull of Apatosaurus:
Berman, D. S.; Mcintosh, J. S., 1978: Skull and relationships of the
Upper Jurassic sauropod Apatosaurus (Reptilia, Saurischia). Bulletin
of Carnegie Museum of Natural History (8): 1-35
Apatosaurus probably possessed a Diplodocus-like, rather than
Camarasaurus-like, skull. Apatosaurus and Diplodocus are closely
related and well separated from Camarasaurus. A Diplodocus-like skull
attributed to Apatosaurus by W. J. Holland over a half century ago is
described for the first time. A cranium and a pair of quadrates that
are very similar to those of Diplodocus are also described and shown
probably to belong to Apatosaurus. Inaccuracies and omissions in
previous descriptions of the skull of Deplodocus have necessitated a
redescription of much of its external features and braincase.
Differences between the skull attributed here to Apatosaurus and that
of Diplodocus are of a subtle proportional and structural nature.
Comparisons of the postcranial skeletons of the Jurassic Apatosaurus,
Diplodocus, and Camarasaurus demonstrate that the former 2 genera
share a large number of significant features and are quite distinct
from the latter. Apatosaurus and Diplodocus, along with the Jurassic
Barosaurus, Cetiosauriscus, Mamenchisaurus, and Dicraeosaurus and the
Cretaceous Nemegtosaurus, should be grouped under Diplodocidae Marsh,
