Transition of Eocene Whales from Land to Sea: Evidence from Bone Microstructure
This study highlights the strong need for homologous sections in comparative microanatomical studies, and the importance of combining information from several bones of the same taxon for improved functional interpretation.
Generalized Osteosclerotic Condition in the Skeleton of Nanophoca vitulinoides, a Dwarf Seal from the Miocene of Belgium
The results suggest that, despite the extreme compactness of long bones of N. vitulinoides and the small size of this taxon, the growth rate of the cortex, and that of the bones in general, did not differ strongly from that of other, larger phocids.
The Anatomy of the Late Miocene Baleen Whale Cetotherium riabinini from Ukraine
Many characteristics of the mysticete skull likely evolved as a result of cranial kinesis, thus leading to multiple instances of morphological convergence across different phylogenetic lineages, as seen in the mallard Anas platyrhynchos.
Unusual Environmental Conditions Preserve a Permian Mesosaur-Bearing Konservat-Lagerstätte from Uruguay
The environmental characterization of the Lower Permian mesosaur-bearing strata of the Mangrullo Formation (Paraná Basin, northeastern Uruguay) has been controversial. Historically, marine conditions
Adaptive Patterns in Aquatic Amniote Bone Microanatomy-More Complex than Previously Thought.
The analysis of the various microanatomical patterns observed in long bones, vertebrae, and ribs of a large sample of (semi-)aquatic extant and extinct amniotes reveals the wide diversity in microan atomical patterns and the variation in combination of these different patterns within a single skeleton.

A combined morphological and microanatomical analysis of vertebrae and ribs of these fossil squamates provides new data about the distribution and variability of this osseous specialization in these taxa.
Functional significance of bone ballastin in the evolution of buoyancy control strategies by aquatic tetrapods
Biomechanical considerations lead to the prediction that a new marine tetrapod clade will typically evolve bone ballast as part of its adaptation to life in water.
Late Miocene megalake regressions in Eurasia
The integrated stratigraphic study shows that the main desiccation episodes occurred between 9.75 and 7.65 million years ago, and identifies four major regressions that correlate with aridification events, vegetation changes and faunal turnovers in large parts of Europe.
Sink or swim? Bone density as a mechanism for buoyancy control in early cetaceans
Analysis of the microstructural features of bone in early and late archaic cetaceans, and in a comparative sample of modern terrestrial, semiaquatic, and aquatic mammals, shows that high bone density is an aquatic specialization that provides static buoyancy control (ballast) for animals living in shallow water, while low bonedensity is associated with dynamic buoyancy Control for animalsliving in deep water.
Evolution of Sirenian Pachyosteosclerosis, a Model-case for the Study of Bone Structure in Aquatic Tetrapods
To document how these features differentiated during sirenian evolution, the ribs of 15 species, from the most basal form (Pezosiren portelli) up to extant taxa, were studied and compared to those of other mammalian species from both morphometric and histological points of view.
