“…We compiled data from the megaloolithid egg localities reported in various basins of southwestern Europe, with special attention on the description and chronostratigraphic occurrence of pathological eggshells. In order to summarize the temporal occurrence of megaloolithid eggs in the entire region, we selected data from long stratigraphic successions of Provence area 17 , 30 , 48 , northern Pyrenees 30 , 32 , and southern Pyrenees 29 , 31 , 33 , 50 , 81 , which range from the upper Campanian to the uppermost Maastrichtian (Fig. 1 , Supplementary Information Fig.…”

The occurrence of dinosaur pathologic eggs in the Late Cretaceous of Europe is well known, but their origin remains unclear. Here we expose the results of a detailed sampling of the conspicuous fossil record of Late Cretaceous titanosaurian eggs (oogenus Megaloolithius) from several southwestern Europe basins. After examining more than 450 samples, we observed a remarkable and statistically supported occurrence of multiple pathologic eggs in a relatively short stratigraphic range at the end of the early Maastrichtian, circa 71-70 Ma. All pathologic specimens exhibit multi-layered eggshell condition, a characteristic related to dystocia, or egg retention within the female uterus for an abnormal prolonged period of time. After exploring various scenarios, the occurrence of pathologic eggs is strongly correlated with an intense dinosaur faunal replacement that occurred during the early Maastrichtian in the Ibero-Armorican Island. Given that inter-species competiveness is proved to produce major affects in ecological communities, our results suggest that pathologies in the eggs of European titanosaurians could be a consequence of an increase in reproductive stress triggered by direct ecological competition between different dinosaurs. Thus, the present study provides a new perspective of how dinosaurs might have been affected by ecological/environmental disturbance.

“…A robust magnetic signal at 42.5 m has an inverse polarity, which could correspond to chron C29r. The two main negative excursions below the K-Pg boundary might be within chron C29r because a recent magnetostratigraphic study in the Aude valley (c. 25 km SW of Lairière) suggests that a major hiatus occurred in the area between chron C31n and the base of chron C29r (Fondevilla et al 2016).…”

Continental-dominated successions are often poorly constrained stratigraphically due to a lack of robust biostratigraphic markers. This study provides the first dataset of δ 13 Corg together with magnetostratigraphic and biostratigraphic data from a thick continental-dominated succession at Lairière (northern Pyrenees, France). This section encompasses the latest Cretaceous up to the Paleocene-Eocene Thermal Maximum interval and is characterized by fluvial deposits, occasionally intercalated with continental carbonates, lacustrine deltaic deposits and shallow marine sediments. This work identifies δ 13 Corg events and assigns them to global δ 13 C geochemical events defined in Pyrenean and Tethyan marine successions, in which the stage boundaries are well calibrated. As the isotopic measurements are performed on dispersed organic matter in sedimentary rocks with a low organic content, we propose that analyses of the signal should take into consideration the depositional environment because variations in the organic matter content might affect the signal. We establish a high-resolution chronostratigraphy in terrestrial Paleocene deposits in the NE Pyrenean zone, recognize a late Selandian interval and define the Paleocene-Eocene Thermal Maximum event.
