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.

The present 3D Dataset contains the 3D model analyzed in the publication : On Roth’s “human fossil” from Baradero, Buenos Aires Province, Argentina: morphological and genetic analysis. The “human fossil” from Baradero, Buenos Aires Province, Argentina, is a collection of skeleton parts first recovered by Swiss paleontologist Santiago Roth and further studied by anthropologist Rudolf Martin. By the end of the 19th century and beginning of the 20th century it was considered as one of the oldest human skeletons from the southern cone. We studied the cranial anatomy and contextualized the ancient individual remains. We discuss the context of the finding, conducted an osteobiographical assessment and performed a 3D virtual reconstruction of the skull, using micro-CT-scans on selected skull fragments and the mandible. This was followed by the extraction of bone tissue and teeth samples for radiocarbon and genetic analyses, which brought only limited results due to poor preservation and possible contamination. We estimate that the individual from Baradero is a middle-aged adult male. We conclude that the revision of foundational collections with current methodological tools brings new insights and clarifies long held assumptions on the significance of samples that were recovered when archaeology was not yet professionalized.

The holotype of Hamadasuchus rebouli Buffetaut 1994 from the Kem Kem beds of Morocco (Late Albian – Cenomanian) consists of a left dentary which is limited, fragmentary and reconstructed in some areas. To aid in assessing if the original diagnosis can be considered as valid, the specimen was CT scanned for the first time. This is especially important to resolve the taxonomic status of certain specimens that have been assigned to Hamadasuchus rebouli since then. The reconstructed structures in this contribution are in agreement with the original description, notably in terms of alveolar count; thus the original diagnosis of this taxon remains valid and some specimens are not referable to H. rebouli anymore.

Using X-ray microtomography, we describe the ossification events during the larval development of a non-teleost actinopterygian species: the Cuban gar Atractosteus tristoechus from the order Lepisosteiformes. We provide a detailed developmental series for each anatomical structure, covering a large sequence of mineralization events going from an early stage (13 days post-hatching, 21mm total length) to an almost fully ossified larval stage (118dph or 87mm in standard length). With this work, we expect to bring new developmental data to be used in further comparative studies with other lineages of bony vertebrates. We also hope that the on-line publication of these twelve successive 3D reconstructions, fully labelled and flagged, will be an educational tool for all students in comparative anatomy.
