The frequency of decompression illness was high among the extinct marine “reptiles” and very low among the marine mammals. Signs of decompression illness are still found among turtles but whales and seals are unaffected. In humans, the risk of decompression illness is five times increased in individuals with Patent Foramen Ovale; this condition allows blood shunting from the venous circuit to the systemic circuit. This right-left shunt is characteristic of the “reptile” heart, and it is… Expand
Hematological convergence between Mesozoic marine reptiles (Sauropterygia) and extant aquatic amniotes elucidates diving adaptations in plesiosaurs
TLDR
Using vascular canal diameter, derived from osteohistological thin-sections, it is shown that inferred red blood cell size significantly increases in pistosauroids compared to more basal sauropterygians, and this change appears to have occurred in conjunction with the dispersal to open marine environments.

Decompression syndrome and the evolution of deep diving physiology in the Cetacea
TLDR
Avascular osteonecrosis was found in the Oligocene basal odontocetes (Xenorophoidea) and in geologically younger mysticetes, such as Aglaocetus, considered as early “experiments” in repetitive deep diving, indicating that they independently converged on their similar specialized diving physiologies.

Stratophenetic analysis of avascular necrosis in turtles : affirmation of the decompression syndrome hypothesis
TLDR
Evolution of physiologic and/or behavioral protective mechanisms appears to be responsible for reduced susceptibility to the underlying decompression syndrome. Expand
Decompression Syndrome and Diving Behavior in Odontochelys, the First Turtle
TLDR
This study suggests that the habit of repetitive diving in turtles was already present in the Late Triassic, but that protective physiological and behavioral adaptations had not yet evolved. Expand
Avascular Necrosis: Occurrence in Diving Cretaceous Mosasaurs
TLDR
A study of vertebrae of extinct giant marine lizards showed the presence of avascular necrosis in two of the three most common genera of these mosasaurs, Platecarpus and Tylosaurus, but absent in a third genus Clidastes. Expand

Decompression sickness (DCS), as clinically diagnosed by reversal of symptoms with recompression, has never been reported in aquatic breath-hold diving vertebrates despite the occurrence of tissueExpand

Abstract Recognition of avascular necrosis through propodial head subsidence in fossils indicates that plesiosaurs were susceptible to decompression syndrome and implies deep, prolonged or repetitiveExpand
Evolution of Fish-Shaped Reptiles (reptilia: Ichthyopterygia) in Their Physical Environments and Constraints
TLDR
Ichthyosaurs were a group of Mesozoic marine reptiles that evolved fish-shaped body outlines that allowed estimation of such characteristics as optimal cruising speed, visual sensitivity, and even possible basal metabolic rate ranges. Expand

TLDR
Clinical context is provided, and an understanding of the variation in reptilian cardiovascular systems, and their functional implications for the assessment and treatment of reptile patients are provided. Expand
Cumulative Sperm Whale Bone Damage and the Bends
TLDR
Sixteen sperm whales from calves to large adults showed a size-related development of osteonecrosis in chevron and rib bone articulations, deltoid crests, and nasal bones, suggesting why some deep-diving mammals show periodic shallow-depth activity and why gas emboli are found in animals driven to surface precipitously by acoustic stressors such as mid-frequency sonar systems.
