Hadrosaur Skin in Latest Issue of Palarch's JVP
I am pleased to announce the publication of the latest paper from the
Raymond M. Alf Museum of Paleontology, describing a hadrosaur dinosaur
skin site from the Kaiparowits Formation of southern Utah. The senior
author on this paper, Lucy Herrero, just graduated from The Webb Schools
(the high school partnered with my museum), and really did a bang-up job
of taking the lead on this project. See the link below to access a free
PDF of the paper.
Herrero, L., and A. A. Farke. 2010. Hadrosaurid dinosaur skin
impressions from the Upper Cretaceous Kaiparowits Formation of southern
Utah, USA. Palarch's Journal of Vertebrate Palaeontology 7(2) (2010): 1-7.
ABSTRACT: Skin impressions from hadrosaurid dinosaurs are relatively
common finds throughout the Cretaceous Western Interior of North
America. A recently discovered specimen from the late Campanian-aged
Kaiparowits Formation of southern Utah is typical for hadrosaurs, with
randomly arranged polygonal tubercles averaging around 4 mm in length
and 3 mm in width. Based on the associated bones, these impressions
likely originated on the thorax of the animal. In contrast with most
previously published finds, the skin is not preserved in perfect
articulation with the skeleton. This suggests a taphonomic mode in which
the skeleton and soft tissues were partially disarticulated prior to burial.
