Introduction
I am a Post Doc fellow at the Bayerische Staatssammlung für Paläontologie und Geologie working with Dr. Gertrud Rößner.
My research focuses on the paleoecology of the Rhinocerotidae throughout their evolutionary history in a context of climatic changes.

The Miocene is a time of major climatic and ecological changes, documented in terrestrial ecosystems. The Rhinocerotidae are abundant and diverse in the fossil record of this epoch, making it a very interesting clade to investigate the paleoecological impact of these changes. Through dental microwear texture analyses (DMTA; short-term diet proxy) a...
The late Miocene is a period of great climatic and ecosystemic changes. The south-eastern Mediterranean region is particularly affected, with increasing aridity and habitat openness. The impact of these changes on rhinocerotids’ ecology has not been studied, although rhinoceroses were a concupious and diverse component of the Miocene mammalian asse...
The late Miocene is a period of increasing aridity and habitat openness in the south-eastern Mediterranean
region. The impact of these changes has not been fully explored regarding rhinocerotids’ ecology, although
rhinoceroses were a major and diverse component of the Miocene mammalian faunas. Here, we investigate
the palaeoecology of rhinocerotid...
Major climatic and ecological changes are documented in terrestrial ecosystems during the Miocene epoch. The Rhinocerotidae are a very interesting clade to investigate the impact of these changes on ecology, as they are abundant and diverse in the fossil record throughout the Miocene. Here, we explored the spatio-temporal evolution of rhinocerotids...
Micro-CT imaging is an increasingly popular method in paleontology giving access to internal structures with a high
resolution and without destroying precious specimens. However, its potential for the study of hypoplasia defects has only recently
been investigated. Here, we propose a preliminary study to test whether hypoplastic defects can be dete...
Le Miocène est une période charnière du Cénozoïque avec des changements climatiques et écosystémiques majeurs, où les forêts tropicales d’Eurasie sont progressivement remplacées par des prairies et savanes herbeuses, à mesure que le climat global se dégrade. Parmi les grands mammifères herbivores, les Rhinocerotidae sont une composante abondante et...
With around 90 species, the mid-Orleanian Béon 1 locality (Occitanie, SW France) yields one of the richest Miocene vertebrate assemblages in Europe. Rhinocerotidae are exceedingly dominant over other faunal components, with dental remains documenting four species: the teleoceratines Brachypotherium brachypus (minimum number of individuals [MNI] ≈5)...
Mortality curves are a valuable tool to study taphonomy and to infer population structure in ancient communities; however, they rely on the precise determination of ontogenetic ages of individual animals, which is often uncertain for fragmentary and isolated fossil remains. In this paper, we develop a new protocol to construct mortality curves for...
Stable carbon and nitrogen isotope ratios of collagen from bone and dentin have frequently been used for dietary reconstruction, but this method is limited by protein preservation. Isotopes of the trace element zinc (Zn) in bioapatite constitute a promising proxy to infer dietary information from extant and extinct vertebrates. The ⁶⁶Zn/⁶⁴Zn ratio...
Poster for the PhD Students' Day at the Institut des Sicences de l'Evolution de Montpellier (ISE-M).
During amelogenesis (enamel formation) stops may occur and lead to the formation of defects when a certain threshold is met (Figure 1; Goodman and Rose, 1990). One of these defects, hypoplasia, is quantitative, non- specific, and permanent.

Rhinoceroses were conspicuous elements in Cenozoic ecosystems, and studying the ecological behavior of extant species might unravel the ecology of their fossil kin. Microwear as a short-term recorder may detect subtle variations in the diet. Dental microwear texture analysis (DMTA) is extensively used to infer paleodiets. Yet, regarding ungulates,...
With about 250 fossil species, rhinoceroses were conspicuous elements in Cenozoic ecosystems and studying the ecological behavior of the five extant species might unravel the ecology of their fossil kin, through uniformitarianism. Dental microwear texture analysis (DMTA) – a short-term recorder of dental abrasion – is extensively used to infer pale...

This project aims at investigating ecological consequences of glaciation events on Rhinocerotidae through the use of an unprecedented approach combining several modern methods based on dental remains. The three main objectives are: 1) to develop an innovative and robust multi-proxy approach to assess the consequences of glaciation events on rhinocerotids, 2) to refine our understanding of Rhinocerotidae ecology
throughout their evolutionary history, and 3) to give palaeoecological inferences constrained by body mass
With my PhD work, I aim at providing insights of paleoenvironments and trophic conditions of extinct rhinocerotoids by using an extensive database on their extant kin.
This long-lasting project, launched in 1994, aims at better characterising the taxonomy, phylogenetic relationships, and evolutionary history of the Rhinocerotoidea (i.e., Hyrachyidae, Amynodontidae, Hyracodontidae, Eggysodontidae, Paraceratheriidae, and Rhinocerotidae). This iconic group of megaherbivores has been roaming most landmasses in Cenozoic times. Their last representatives, i.e. Asian and African rhinos, are among the most critically endangered mammalian species today.
