Histological evidence of trauma in tusks of southern African dicynodonts.
Palaeontologia Africana 53: 75-80
Dicynodonts were a clade of globally-distributed therapsids known for their abundance in the fossil record and for surviving the Permo-Triassic mass extinction. The group had distinctive dental adaptations including a beak and, in many species, paired maxillary tusks. The function of these tusks has long been of interest, yet remains poorly understood.We report here on two instances of unusual morphology in tusk dentine from specimens of: 1) Lystrosaurus from the Karoo Basin of South Africa and, 2) an unidentified dicynodontoid from the Luangwa Basin of Zambia. In both, the cross-sectional shape of the tusk root is lobed and infolded, which histological features suggest is a result of abnormal dentine deposition. We infer that this abnormal morphology is likely the consequence of trauma given its reparative nature and structural similarities to trauma-related morphologies reported in the tusks of modern elephants. This study demonstrates that histological sampling of dicynodont tusks can shed light on the biology of this important clade of therapsids.

Permian-Triassic terrestrial ecosystems of the Dolomites (Southern Alps): Field trip on the occasion of the Paleodays 2018.
Geo.Alp 15: 5-36 (in English)
This paper provides a guide to the field trip of the 2018 edition of the Paleodays, the annual congress of the Società Paleontologica Italiana (Trento, 6â8 June 2018), dedicated to the terrestrial ecosystems of the Dolomites between the late Permian and the Middle Triassic. It is structured into three stops (Fig. 1). We will first visit two outcrops located near Tramin/Termeno, where the PermianâTriassic boundary is exposed, and in the Bletterbach Gorge, where the late Permian crops out in an extensive and spectacular succession. The third stop offers a visit to the Geological Museum of the Dolomites, in Predazzo, which allows us to discuss about carbonate platforms and the diversification of plants and tetrapods in the Middle Triassic.

Lâicnoassociazione a tetrapodi del Bletterbach (Trentino Alto-Adige) e le sue relazioni con gli ecosistemi terrestri di fine Permiano.
The tetrapod ichnoassociation of the Bletterbach (Trentino Alto-Adige) and its place among Late Permian terrestrial ecosystems.
Geo.Alp 14: 63-83 (in Italian)
In this paper we provide an updated review of the tetrapod footprint association discovered in the Bletterbach Gorge (Southern Alps, NE Italy) from the '70s. We provide global-scale analysis integrating paleontological and climatic data highlight the importance of the Bletterbach ichnoassociation as key reference for low-latitude terrestrial ecosystems during the Lopingian (Late Permian). Our results provide evidence for a tight correlation between the distribution of the main herbivorous tetrapod clades (dicynodonts, pareiasaurs, captorhinids) and the latitudinal climatic zonation.
