Ontogeny and miniaturization of Alvarezsauridae (Dinosauria, Theropoda)
Biological Communications, 2023 The ontogenetic status of the known specimens of alvarezsaurid theropod dinosaurs is revised. We present histological data that the holotype of Parvicursor remotus from the Upper Cretaceous Barungoyot Formation of Mongolia is not an adult individual, as ...
