Abstract About 50% of all animal species are considered parasites. The linkage diversity to a parasitic lifestyle is especially evident in the insect order Hymenoptera. However, fossil evidence for host–parasitoid interactions extremely rare, rendering hypotheses on evolution parasitism assumptive. Here, using high-throughput synchrotron X-ray microtomography, we examine 1510 phosphatized fly pupae from Paleogene France and identify 55 parasitation events by four wasp species, providing...
Abstract The functional anatomy of the hindlimb bipedal dinosaurs has been intensively studied. Yet, surprisingly little work done concerning adaptation digits for terrestrial locomotion. While complete and articulated pes skeletons are scarce, shape is abundantly recorded by fossil footprints. We elucidate significance footprint size locomotion using a large sample (n = 303) tridactyl dinosaur footprints from broad range geographical localities time slots. Size variation characterized...
Synopsis Dinosaur nesting biology has been an intriguing research topic, though dinosaur behaviors were relatively less illuminated because of the constraints fossil record. For instance, hatching asynchrony, where eggs in a single clutch hatch at different times, is unique to modern neoavian birds but was also suggested be present oviraptorid dinosaurs based on possible partial four embryo-containing from Mongolia. Unfortunately, unequivocal evidence for origination these lacking. Here we...
The evolution of carnassial teeth in mammals, especially the Carnivora, has been subject many morphometric and some dental topographic studies. Here, we use a combination analysis (Dirichlet normal energy) 3D geometric morphometrics less high carnassialized lower carnivoran, dasyuromorph hyaenodont taxa. Carnassial crown curvature, as indicated by Dirichlet energy, is lesser low higher teeth, where it influenced reduction features such cusps crests. PC1 linked to enlargement blade, talonid...
