Dear DM,

A bunch of new papers just came in on Morrison critters, and since you
have some interest (and a lot of experience) with that formation I
thought's I'd pass them along.

This genus, Haplocanthosaurus, is special to me because it may have
been what got me excited by dinosaurs to begin with as it has been on
display at the Cleveland Museum since I was a little kid.

A new paper in open access:

John R. Foster & Mathew J. Wedel (2014)
Haplocanthosaurus (Saurischia: Sauropoda) from the lower Morrison
Formation (Upper Jurassic) near Snowmass, Colorado.
Volumina Jurassica XII (2): 197–210
DOI: 10.5604/17313708 .1130144

A small sauropod dinosaur collected from the Rocky Mountains of
central Colorado (north of the Elk Range, Pitkin County) is assigned
to the rare genus Haplocanthosaurus. The specimen, MWC 8028, consists
of four dorsal centra, five partial ribs, the sacrum, five caudal
vertebrae, three chevrons, five partial neural spines and many
fragments and is from the lower third of the Upper Jurassic Morrison
Formation. The dorsal vertebrae are procamerate, and on the sacral
vertebrae the neural arch peduncles are vertically elongate and the
neural spines are strongly reclined. The only sauropod from the
Morrison Formation that shares these characters is Haplocanthosaurus
and based on those characters MWC 8028 is referred to
Haplocanthosaurus. This is at most the tenth specimen and the seventh
locality for this sauropod, all within the Morrison Formation.
