Summary: Despite the discovery of many dinosaur eggs and nests over the past 100 years, articulated in-ovo embryos are remarkably rare. Here we report an exceptionally preserved, articulated oviraptorid embryo inside an elongatoolithid egg, from the

Carcharodontosauria is a group of medium to large-sized predatory theropods, distributed worldwide during the Cretaceous. These theropods were probably the apex predators of Asiamerica in the early Late Cretaceous prior to the ascent of tyrannosaurid

In the accompanying Comment, Choi et al. dispute morphological, histological, geochemical and biomechanical evidence for a soft-shelled egg in Mussaurus, an Early Jurassic sauropodomorph, based on three main assertions, namely that: (1) the carbonate

The fossil dinosaur embryo ‘Baby Louie’ and associated clutch of eggs were first discovered in the early 1990s, but were not formally described. Here, the authors identify the specimen as an embryo and eggs of the new large caenagnathid oviraptor

The dinosaur–bird transition involved several anatomical, biomechanical, and physiological modifications of the theropod bauplan. Non-avian maniraptoran theropods, such as Troodon , are key to better understand changes in thermophysiology and repro

The albertosaurines Albertosaurus sarcophagus and Gorgosaurus libratus are among the best represented tyrannosaurids, known from nearly complete growth series. These specimens provide an opportunity to study mandibular biomechanical properties and to

Calcified eggshell protect developing embryos against environmental stress and contributes toreproductive success. Since modern crocodilians and birds lay hard-shelled eggs, this eggshelltype has also been inferred for nonavian dinosaurs. Known dinos

Known from dozens of specimens discovered since the early 20th century, Gorgosaurus libratus has arguably contributed more than any other taxon to our understanding of the life history of tyrannosaurids. However, juvenile material for this taxon is r
