Stomach histology of Crocodylus siamensis and Gavialis gangeticus reveals analogy of archosaur “gizzards”, with implication on crocodylian gastroliths function

open access: yesActa Herpetologica, 2020
Two groups of extant Archosauria, Crocodylia and Neornithes, have two-chambered stomachs and store gastroliths inside their “gizzards”. Morphological similarities of the “gizzards” lead some previous studies to assume that the presence of this structure,
