Article Reference Morphological study of the anterior dentition in Raoellidae (Mammalia, Artiodactyla), new insight on their dietary habits
Raoellidae are small artiodactyls from the Indian subcontinent closely related to stem cetaceans. They bring crucial information to understand the early phase of the land-to- water transition in Cetacea. If they are considered to be partly aquatic, the question of their dietary habits remains partly understood due to their “transitional” morphology. Raoellidae are largely documented by their cheek teeth and getting a better knowledge of their anterior dentition constitutes an additional proxy to discuss their feeding habits. In this work, we document the anterior dentition of Indohyus indirae from an unprecedented sample of in situ and isolated teeth from the locality of East Aiji-2 in the Kalakot area (Rajouri district, India). We propose identification criteria for upper and lower incisors and canines in raoellids. Based on CT scan data, virtual reconstruction of in situ dentition, and identification of the isolated incisors and canines, we reconstruct a composite anterior dentition of Indohyus supported by the correspondence of wear facets between upper and lower teeth. This constitutes the first attempt at reconstruction of the anterior dentition of a raoellid. We show that the upper incisors are caniniform and very similar morphologically, whereas the lower incisors are pointed but remain incisiform and quite different from one another. We also describe noticeable intraspecific variation, at the level of upper canines, suggesting a potential sexual dimorphism in this species. Upper and lower incisors are recurved, with the upper incisor row arranged on a widely opened arch. Taken altogether the anterior dentition forms a grasping device, allowing the animal to capture and secure food, a characteristic shared with stem cetaceans. This would mark the first step towards the carnivorous diet in these peculiar artiodactyls.

Article Reference Bioerosional marks in the shells of two sea turtle taxa from the middle Eocene of Belgium
This study analyses the diverse types of bioerosion marks on the shells of two sea turtle specimens from the Lutetian (middle Eocene) of Belgium. The objective is to understand the physical stressors affecting these organisms in ancient marine environments and to identify the potential factors responsible for these changes. The first specimen, the holotype of Eochelone brabantica, presents multiple erosive anomalies on its costal plates. The second individual, corresponding to Puppigerus camperi, exhibits different types of shell deviations, also of an erosive character. The combination of macroscopic and imaging techniques (i.e., CT scanning and 3D surface scanning) allow us the precise observation and identification of the different alterations. Comparative analyses suggest several external factors as potential causes of the anomalies of the two specimens (i.e., invertebrate feeding traces and trauma). This detailed examination provides specific insights into the types and causes of shell alterations in these Eocene turtles, offering a clearer understanding of their interactions in the marine ecosystem in which they lived.

Article Reference India as a “Noah’s Ark” before Collision with Eurasia: Palaeoenvironment and Palaeobiogeography of the Continental Early Eocene Vertebrate Fauna of Gujarat
For the past twenty years, an Indian-American-Belgian team carried out twelve seasons of collaborative fieldwork in search of vertebrates from the Cambay Formation in lignite mines of Gujarat, western India. Here is a summary of our main discoveries in the Vastan, Mangrol, and Tadkeshwar mines, including an updated overview of the whole vertebrate fauna. The fauna is around 54.5 million years old, representing tropical rainforest conditions in a coastal brackish palaeoenvironment. It includes the earliest modern mammals from the Indian subcontinent as well as endemic taxa. The most important result at the palaeobiogeographical level is the discovery of several vertebrate taxa of Gondwanan affinities, indicating that the early Eocene was a crucial period in India when Laurasian taxa with western European affinities co-existed with relict taxa from Gondwana before the actual collision of India and Eurasia. Terrestrial faunas could have dispersed to or from Europe when the Indian subcontinent came into contact, episodically, with different island blocks, such as the Kohistan-Ladakh island-arc system, along the northern margin of Neotethys Ocean.

Article Reference 3D models related to the publication: Morphological study of the anterior dentition in Raoellidae (Mammalia, Artiodactyla), new insight on their dietary habits
The present 3D dataset contains 3D models of new material from the middle Eocene of the Upper Subathu Formation in the Kalakot area (India), documenting the anterior dentition of the raoellid Indohyus indirae. Raoellidae are closely related to stem cetaceans and bring crucial information to understand the earliest phase of land to water transition in Cetacea.
