This project presents the osteological connexions of the petrosal bone of the extant Hippopotamidae Hippopotamus amphibius and Choeropsis liberiensis by a virtual osteological dissection of the ear region. The petrosal, the bulla, the sinuses and the major morphological features surrounding the petrosal bone are labelled, both in situ and in an exploded model presenting disassembly views. The directional underwater hearing mode of Hippopotamidae is discussed based on the new observations.

Megatherium americanum MNHN.F.PAM276 View specimen

M3#14 This model corresponds to a virtually reconstructed bony labyrinth of the right inner ear of the skull MNHN-F-PAM 276, attributed to the extinct giant ground sloth Megatherium americanum. The fossil comes from Pleistocene deposits at Rio Salado (Prov. Buenos Aires, Argentina). The bony labyrinth of Megatherium shows semicircular canals that are proportionally much larger than in the modern two-toed and three-toed sloths. The cochlea in Megatherium shows 2.5 turns, which is a rather high value within Xenarthra. Overall, the shape of the bony labyrinth of Megatherium resembles more that of extant armadillos than that of its extant sloth relatives. Type: "3D_surfaces" doi: 10.18563/m3.sf14   state:published

Current knowledge on the skeletogenesis of Chondrichthyes is scarce compared with their extant sister group, the bony fishes. Most of the previously described developmental tables in Chondrichthyes have focused on embryonic external morphology only. Due to its small body size and relative simplicity to raise eggs in laboratory conditions, the small-spotted catshark Scyliorhinus canicula has emerged as a reference species to describe developmental mechanisms in the Chondrichthyes lineage. Here we investigate the dynamic of mineralization in a set of six embryonic specimens using X-ray microtomography and describe the developing units of both the dermal skeleton (teeth and dermal scales) and endoskeleton (vertebral axis). This preliminary data on skeletogenesis in the catshark sets the first bases to a more complete investigation of the skeletal developmental in Chondrichthyes. It should provide comparison points with data known in osteichthyans and could thus be used in the broader context of gnathostome skeletal evolution.

Considerable morphological variations are found in the middle ear among mammals. Here I present a three-dimensional atlas of the middle ear ossicles of eulipotyphlan mammals. This group has radiated into various environments as terrestrial, aquatic, and subterranean habitats independently in multiple lineages. Therefore, eulipotyphlans are an ideal group to explore the form-function relationship of the middle ear ossicles. This comparative atlas of hedgehogs, true shrews, water shrews, mole shrews, true moles, and shrew moles encourages future studies of the middle ear morphology of this diverse group.

Turtles are one of the most impressive vertebrates. Much of the body is either hidden in a shell or can be drawn into it. Turtles impress with their individual longevity and their often peaceful disposition. Also, with their resilience, they have survived all extinction events since their emergence in the Late Triassic. Today's diversity of shapes is impressive and ranges from the large and high domed Galapagos turtles to the hamster-sized flat pancake turtles. The holotype of one of the oldest fossil turtles, Proganochelys quenstedtii, is housed in the paleontological collection in Tübingen/Germany. Since its discovery some years before 1873, P. quenstedtii has represented the 'prototype' of the turtle and has had an eventful scientific history. It was found in Neuenhaus (Häfner-Neuhausen in Schönbuch forest), Baden-Württemberg, Germany, and stems from Löwenstein-Formation (Weißer Keupersandstein), Late Triassic. The current catalogue number is GPIT-PV-30000. The specimen is listed in the historical inventory “Tübinger Petrefaktenverzeichnis 1841 bis 1896, [folio 326v.]“, as “[catalogue number: PV]16549, Schildkröte Weiser Keupersandstein Hafnerhausen” [turtle from White Keuper Sandstone]. Another, more recent synonym is “GPIT/RE/9396”. The same specimen was presented as uncatalogued by Gaffney (1990). Here we provide a surface scan of the steinkern for easier access of this famous specimen to the scientific community.
