Here we provide atlases of 3D brain (endocast) reconstructions for <jats:italic>Alligator mississippiensis<\/jats:italic> (alligator) and <jats:italic>Struthio camelus<\/jats:italic> (ostrich) through ontogeny, prepared as digital restorations from CT scans of stained head and dry skull specimens. Our morphometric analysis confirms that ostrich brains do not change significantly in shape during postnatal growth, whereas alligator brains unfold from a cramped bird\u2010like shape in the hatchling to an elongate, straight structure in the adult. We confirm that birds exhibit paedomorphic dinosaur endocranial traits such as retaining an enlarged and compact brain shape in the adult, whereas crocodiles show peramorphic traits where the brain elongates with growth as the skull elongates. These atlases of ontogenetic stages of modern bird and crocodilian endocrania provide a basis for comparison of non\u2010avian dinosaur endocasts and consideration of the divergence of the \u201cavian\u201d and \u201ccrocodilian\u201d modes of brain development and heterochronic change on phylogenies.<\/jats:p>","DOI":"10.1002\/ar.24579","type":"journal-article","created":{"date-parts":[[2020,12,12]],"date-time":"2020-12-12T08:00:25Z","timestamp":1607760025000},"page":"1759-1775","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Ontogenetic endocranial shape change in alligators and ostriches and implications for the development of the non\u2010avian dinosaur endocranium"],"prefix":"10.1002","volume":"304","author":[{"given":"Krishna","family":"Hu","sequence":"first","affiliation":[{"name":"School of Earth Sciences University of Bristol  Bristol UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2104-4187","authenticated-orcid":false,"given":"J.
