TL;DR: A comprehensive survey of the Cenozoic deposits along the Quebrada Cachiyacu near Contamana in Peruvian Amazonia is presented in this paper, where 34 fossil-bearing localities identified have yielded a diversity of fossil remains, including vertebrates, mollusks, arthropods, plant fossils, and microorganisms, ranging from the early Paleocene to the late Miocene-?Pliocene (>20 successive levels).

TL;DR: Two particular events can be pinpointed in the history of the Squaliformes: the first occurs after the major Cenomanian-Turonian anoxic event and the second one after the Cretaceous/Tertiary crisis.

TL;DR: Results indicate that with the exception of high taxonomic ranks (orders), the selachian fossil record is by far imperfect, particularly for generic and post-Triassic data.

TL;DR: X-ray microtomography is used to investigate a newly discovered sirenian petrosal from the Eocene of Tunisia, which represents the oldest occurrence of sirenians in Africa and supports their African origin.

TL;DR: The first detailed comparative description of teeth belonging to most of the living and fossil mobulids is performed, providing clues to the evolutionary history of this clade since the Early Eocene, including the gradual lack in tooth interlocking toward the filter-feeding strategy, whereas the preservation of cusped teeth without feeding function in modern filter-feeder mobulid is interpreted as a tool for precopulatory purposes.
