The cardiovascular hemodynamics of Crocodilia
Journal of Surgical Research, 1961Summary Physiologic studies of the central circulation were carried out in three large specimens of Alligator mississipiensis , utilizing direct intracardiac pressure measurements, selective angiocardiography and indicator dilution curves. In the order Crocodilia, in which the interventricular septum is intact, the pulmonary artery pressure was ...

The chromosomes of the order Crocodilia
Cytogenetics, 2008The somatic karyotypes of the 21 surviving species of the order Crocodilia are presented. The population surveyed totals 71 animals, with representatives of both sexes in 13 species. No karyotypic differences were observed among the multiple specimens within a given species or subspecies.

The Evolution and Classification of the Crocodilia
Journal of Geology, 1934Studies during the last fifteen years in connection with the preparation of a monograph on the fossil Crocodilia have revealed the lack of an adequate modern classification which includes an important Triassic form recently described by Mr. Barnum Brown.

The Eustachian Tubes in the Crocodilia
Copeia, 1946THE eustachian tubes in the Crocodilia probably are unique because of the complexity of their development. This is a fact that is not very widely recognized among anatomists or herpetologists, although it has been noted in the literature by various authors during the past century.

The external ear in Crocodilia
Proceedings of the Zoological Society of London, 1955Summary. Crocodilians possess a slit‐like external auditory meatus, bounded above by a large superior ear‐flap, and below and in front by a small inferior ear‐flap. The anterior part of the meatus in living animals is usually open when the top of the head is out of water and closed when it is submerged.

The Zoogeography of the Crocodilia
Copeia, 1968Tertiary and became greatly reduced with the cooling which began during the later part of this period. The present distribution is a relict of the early Tertiary radiation. Crocodiles are sensitive to climatic fluctuation and their distribution correlates well with the climatic changes of the Tertiary as represented by fossil floras. The endemic groups
