Using these data, researchers have inferred limb orientations, postures, gaits, ecological functions and even phylogenetic trends within clades. However, important areas of concern remain unaddressed; for example, how does ROM at a forelimb joint change after soft tissues are lost in archosaurs? And are fossil ROM methodologies amenable to reproducibility and statistical analysis? Here, we investigated these questions using the extant phylogenetic bracket of dinosaurs. Repeated measures of elbow joint ROM from Struthio camelus and Alligator mississippiensis forelimbs were statistically analyzed as they were sequentially dissected through five levels of tissue removal treatment. Our data indicate that there are no statistically significant differences in repeated measures of ROM between observers who use the same techniques. Extrinsic soft tissues, such as integument, muscles and ligaments were found to impede ROM at the elbow joint. Intrinsic soft tissues, such as articular cartilage, may increase ROM. The hypothesis that the articular surfaces of the bones within the elbow joints of archosaurs provide a general approximation of mobility is supported. Final ROMs were less than the initial ROMs in both taxa, which suggests that prior reports of elbow joint ROMs in degrees for nonavian dinosaurs may represent conservative estimates. We conclude that if observer bias and other variables are controlled for, ROM studies of fossil archosaur limbs can obtain useful degree data for inferring joint mobility in vivo.<\/jats:p>","DOI":"10.1242\/jeb.069567","type":"journal-article","created":{"date-parts":[[2012,5,23]],"date-time":"2012-05-23T17:28:46Z","timestamp":1337794126000},"page":"2030-2038","source":"Crossref","is-referenced-by-count":53,"title":["A test of the validity of range of motion studies of fossil archosaur elbow mobility using repeated-measures analysis and the extant phylogenetic bracket"],"prefix":"10.1242","volume":"215","author":[{"given":"Joel D.","family":"Hutson","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, Northern Illinois University, 1425 West Lincoln Highway, DeKalb, IL 60115-2825, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelda N.","family":"Hutson","sequence":"additional","affiliation":[{"name":"Department of Earth Science, College of Lake County, 19351 West Washington Street, Grayslake, IL 60030-1198, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042506354527300_R1","volume-title":"Geschichte und Methode der Rekonstruktion vorzeitlicher Wirbeltiere.","author":"Abel","year":"1925"},{"key":"2021042506354527300_R2","first-page":"48","article-title":"Mouvements de l\u2019avant-bras chez les oiseaux","volume":"28","author":"Alix","year":"1863","journal-title":"Bull.
