ABSTRACT The first diagnostic sirenian material from Madagascar and, more broadly, the first diagnostic pre-Pleistocene Cenozoic mammal material recovered from the island is reported. Eotheroides lambondrano is a new species of sirenian collected from middle Eocene nearshore marine deposits in the Mahajanga Basin of northwestern Madagascar. The recovered material consists of a nearly complete adult skull (including the first complete rostrum known for Eotheroides) and several portions of… 
First adequately-known quadrupedal sirenian from Eurasia (Eocene, Bay of Biscay, Huesca, northeastern Spain)
TLDR
Sirenians are the only extant herbivorous mammals fully adapted to an aquatic lifestyle and Sobrarbesiren is recovered as the sister taxon of Dugongidae and represents a transitional stage of adaptation to aquatic life between the amphibious quadrupedAL prorastomids and the aquatic quadrupedal protosirenids.
Gondwanatheria and ?Multituberculata (Mammalia) from the Late Cretaceous of Madagascar
TLDR
Five new specimens from the Late Cretaceous of Madagascar, including a virtually complete lower molariform cheek tooth, two fragmentary cheek teeth, and a fragmentary lower incisor are referred to the Sudamericidae (Gondwanatheria).
Sokatra, a New Side-Necked Turtle (Late Cretaceous, Madagascar) and the Diversification of the Main Groups of Pelomedusoides
TLDR
The deep phylogenetic roots of Sokatra indicates the presence of its lineage on Madagascar prior to the beginning of the Late Cretaceous.
New Miocene sirenians from Nosy Makamby, northwestern Madagascar
ABSTRACT The near lack of vertebrate fossils from the Cenozoic of Madagascar has left many of the details regarding the origin and evolution of the island’s extant faunas unknown. However, recent
Cranial Remain from Tunisia Provides New Clues for the Origin and Evolution of Sirenia (Mammalia, Afrotheria) in Africa
TLDR
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.

Newly discovered remains of the early Middle Eocene (Lutetian) sirenian Protosiren (Protosirenidae) in shark tooth rich conglomerates from a coastal delta environment northwest of the European
A middle - late Eocene neoselachian assemblage from nearshore marine deposits, Mahajanga Basin, northwestern Madagascar
TLDR
This fauna represents the first Cenozoic neoselachian fossil record from the Eocene of Madagascar and broadens the understanding of their evolutionary and biogeographic history in the southern hemisphere during this time.
An early Miocene dugongine (Sirenia: Dugongidae) from Panama
ABSTRACT Herein, we describe a new early Miocene dugongine from marine deposits of the Culebra Cut (Gaillard Cut) of the Panama Canal. The new taxon, Culebratherium alemani, gen. et sp. nov.,

New Species of Protosiren (Mammalia, Sirenia) from the Early Middle Eocene of Balochistan (Pakistan)
TLDR
Protosiren eothene is the oldest and smallest species of Protosiren known to date and retains synovial articulations on rib heads, and it is about 10-12% smaller in linear dimensions than P. fraasi from the early middle Eocene of Egypt.

A Small Collection of Fossil Vertebrates from the Middle Eocene Kuldana and Kohat Formations of Punjab (Pakistan)
TLDR
Discovery of a small concentration of mammal specimens at one locality suggests that there is very good potential for the discovery of additional middle Eocene mammals in the Kuldana Formation and its lateral equivalents.

Catalogus Mammalium tam viventium quam fossilium
TLDR
A new catalogue of Mammals is much wanted, and will be of great use to the many workers in that group of animals, although the work appears to have been performed in a satisfactory manner, though it would not be difficult to point out a certain number of slips and errors.

In the lower beds remains of a Sirenian are very common, and several more or less complete skulls associated with some portions of the skeleton were found. The skull in most respects resembles that
