“…The Bajo de la Carpa Formation rests conformably on the Plottier Formation and is capped by deposits of the Anacleto Formation (Figure 3) [19]. Unlike other regions of the Neuquén Basin, the Santonian rocks of this formation were deposited by fluvial and aeolian systems [20] as well as extensive flood plains [18], [19] (Figure 3). …”

“…Regionally, this system formed in an arid and dry continental climate via aeolian deposition [18], [19]; there is clear variation from fluvial systems to distal floodplains across the sequence with increasing participation of aeolian sediments [19]. The palaeoeonviroment inferred for the university campus area consists of aeolian deposition that created large dunes and inter-dune lagoon basins skirted by fluvial deposits, criss-crossed by streams and seasonal or ephemeral water bodies [18], [21].…”

A Large Accumulation of Avian Eggs from the Late Cretaceous of Patagonia (Argentina) Reveals a Novel Nesting Strategy in Mesozoic Birds

We report the first evidence for a nesting colony of Mesozoic birds on Gondwana: a fossil accumulation in Late Cretaceous rocks mapped and collected from within the campus of the National University of Comahue, Neuquén City, Patagonia (Argentina). Here, Cretaceous ornithothoracine birds, almost certainly Enanthiornithes, nested in an arid, shallow basinal environment among sand dunes close to an ephemeral water-course. We mapped and collected 65 complete, near-complete, and broken eggs across an area of more than 55 m2. These eggs were laid either singly, or occasionally in pairs, onto a sandy substrate. All eggs were found apparently in, or close to, their original nest site; they all occur within the same bedding plane and may represent the product of a single nesting season or a short series of nesting attempts. Although there is no evidence for nesting structures, all but one of the Comahue eggs were half-buried upright in the sand with their pointed end downwards, a position that would have exposed the pole containing the air cell and precluded egg turning. This egg position is not seen in living birds, with the exception of the basal galliform megapodes who place their eggs within mounds of vegetation or burrows. This accumulation reveals a novel nesting behaviour in Mesozoic Aves that was perhaps shared with the non-avian and phylogenetically more basal troodontid theropods.

crocodilian Iharkutosuchus makadii, that exhibit pathological traits on their surface. These 26 pathologies can be described as shallow and deep pits, bisected pits, scores, and in the case of 27 the skull roof also a hole piercing through the entire bone thickness. Morphological and bone 28 histological features of these pathological traits imply that they probably represent bite marks. had conical teeth and therefore might have been responsible for the bite marks in both cases. 37The inferred tooth marks on the dorsal surface of the Iharkutosuchus skull roof indicate a 38 predator-prey interaction rarely documented between two different crocodilian taxa rather 39 than antagonistic behaviour over common resources. Nevertheless, to draw firm conclusions Introduction 45The study of bite marks represents a significant research field in paleontology because 46 such traces on the fossil bone surface indicate a factual interaction between two animals 47(either antagonistic or predator-prey interaction). As such, it may provide direct evidence on 48 the feeding behaviour of extinct carnivores and information on the trophic structure of the 49 palaeocommunity. Crushing the bones of the prey to access the nutritious marrow is a 50 common behaviour among mammalian carnivores and related traces are frequently found in 51 modern ecosystems as well as in fossil assemblages (e.g. Haynes, 1983;Weigelt, 1989; 52 Fiorill, 1991; Domínguez-Rodrigo, 1999;Hu et al., 2005; Faith and Behrensmeyer, 2006; 53 Faith et al., 2007). However, direct evidence of bones showing such mammal-like bone-54 crushing activity is quite rare among sauropsid groups due to their usually different dentition 55 and feeding behaviour (Fiorillo, 1991; Farlow and Holtz, 2002;Hone and Rauhut, 2009; 56 D'Amore and Blumenschine, 2009). The number of studies focusing on fossil bones with 57 sauropsid bite marks has increased lately (Fiorill, 1991; Carpenter, 1998;Jacobsen, 1998; 58 Farlow and Holtz, 2002; Avilla et al., 2004; Buffetaut et al., 2004;Hone and Rauhut, 2009; 59 Fiorelli, 2010;Longrich et al., 2010;Milàn et. al., 2010;Schwimmer, 2010; Bell, et al., 2012; 60 Noto et al., 2012; Boyd et al., 2013), and some experiments have been conducted on the 61 feeding traces of extant sauropsids as well (Njau and Blumenschine, 2006; D'Amore and 62 Blumenschine, 2009, 2012;Vasconcellos and Carvalho, 2010). In most investigations of 63 sauropsid feeding behaviour, the study objects were restricted to dinosaurs (e.g. Fiorill, 1991; 64 Erickson and Olson, 1996; Carpenter, 1998;Jacobsen, 1998; Farlow and Holtz, 2002; Rogers 65 et al., 2003; Fowler and Sulivan, 2006;Hone and Rauhut, 2009;Peterson et al., 2009; Hone et 66 al., 2010;Paik et al., 2011) while feeding traces of other sauropsids, such as crocodilians, 67have only recently received attention (e.g. Karl and Tichy, 2004; Njau and Blumenschine, 68 2006;2012Fiorelli 2010Schwimmer, 2010;Vasconcellos and Carvalho, 2010; Boyd et al., 69 4 2013;Martin, 2013).
