Late Early Jurassic Mammaliaforms from Huizachal Canyon, Tamaulipas, México (2008)
Marisol Montellano, James A. Hopson, James M. Clark
Previous reports of the fossil vertebrates from the upper Lower Jurassic La Boca Formation of Tamaulipas, México, presented descriptions of a tritylodontid therapsid, a burrowing diapsid,...
Flight Test Techniques for Aircraft Parameter Estimation in Ground Effect (2006)
The effect of ground proximity on the performance and handling of an aircraft has received extensive study, particularly in the wind tunnel. Previous research, however, provides few consistent...
PROBLEMS DUE TO MISSING DATA IN PHYLOGENETIC ANALYSES INCLUDING FOSSILS: A CRITICAL REVIEW (2003)
MAUREEN KEARNEY, JAMES M. CLARK
We review the widespread notion that the inclusion of taxa scored for relatively few characters is problematic in phylogenetic analyses. Taxa scored for few characters may lead to lack of resolution,...
Osteology and Relationships of Byronosaurus jaffei (Theropoda: Troodontidae) (2003)
PETER J. MAKOVICKY, MARK A. NORELL, JAMES M. CLARK, TIMOTHY ROWE
The troodontid Byronosaurus jaffei is known from two specimens from adjacent localities in the Nemegt basin, Ömnögov Aimag, Mongolia. These specimens are composed of well-preserved cranial material...
JAMES M. CLARK, MARK A. NORELL, TIMOTHY ROWE
We describe the skull of the holotype of Citipati osmolskae, one of the best preserved oviraptorid skulls known. The skull preserves stapes and epipterygoids, and the mandible preserves a slender...
A new therizinosaur from the Lower Jurassic lower Lufeng Formation of Yunnan, China (2001)
XING XU, XIJIN ZHAO, JAMES M. CLARK
A specimen collected from the Lower Jurassic Lower Lufeng Formation of Yunnan, China, represents a new genus and species of therizinosauroid theropod. It comprises an incomplete left mandibular ramus...
An Embryonic Oviraptorid (Dinosauria: Theropoda) from the Upper Cretaceous of Mongolia (2001)
MARK A. NORELL, JAMES M. CLARK, LUIS M. CHIAPPE
An embryonic oviraptorid skeleton is described within an egg from the Late Cretaceous Djadokha Formation of Ukhaa Tolgod, Mongolia. The specimen comprises the ventral part of the skull and most of...
JAMES M. CLARK, HANS-DIETER SUES, DAVID S. BERMAN
An articulated partial skeleton, including a nearly complete skull and left forelimb, of a crocodylomorph reptile from the Upper Triassic Chinle Formation of Ghost Ranch, New Mexico, is referable to...
Assessing thinking in middle school students : a thesis / (1997)
Thesis (M.A.)--University of Massachusetts Boston, 1997.
DNA polymerases catalyze the addition of deoxyribonucleotides onto DNA primers in a template-directed manner. The requirement for template instruction distinguishes these enzymes from other...
Thymlne glycol lesions terminate chain elongation by DNA polymerase I in vitro (1986)
Clark, James M., Beardsley, G.Peter
Single-strand circular DNA from bacteriopbage H13mp9 was chemically modified with osmium tetroxide to introduce specifically cis-thymine glycol lesions, a major type of DNA damage produced by...
A basal ceratopsian with transitional features from the Late Jurassic of northwestern China
Xu, Xing, Forster, Catherine A, Clark, James M, Mo, Jinyou
Although the Ceratopsia and Pachycephalosauria, two major ornithischian groups, are united as the Marginocephalia, few synapomorphies have been identified due to their highly specialized body-plans....
Intravascular Neutrophil Activation Due to Carbon Monoxide Poisoning
Thom, Stephen R., Bhopale, Veena M., Han, Shih-Tsung, Clark, James M., Hardy, Kevin R.
Rationale: We hypothesized that platelet–neutrophil interactions occur as a result of acute carbon monoxide (CO) poisoning, and subsequent neutrophil activation triggers events that cause...
