Despite nearly two centuries of investigation, a comprehensive understanding of dinosaur
biology has proven intractable. The recent development of means to study tissue-level …

In the mid-19th century, the discovery that bone microstructure in fossils could be preserved
with fidelity provided a new avenue for understanding the evolution, function, and …

Fossil bone microanalyses reveal the ontogenetic histories of extinct tetrapods, but
incomplete fossil records often result in small sample sets lacking statistical strength. In …

The sutures of the skulls of vertebrates are generally open early in life and slowly close as
maturity is attained. The assumption that all vertebrates follow this pattern of progressive …

The ontogeny of early-diverging dinosauromorphs is poorly understood because few
ontogenetic series from the same species-level taxon are known and what is available has …

Sauropod dinosaurs include the largest terrestrial animals and are considered to have
uninterrupted rapid rates of growth, which differs from their more basal relatives, which have …

Decuriasuchus quartacolonia is a middle‐sized basal “rauisuchian”(Pseudosuchia,
Loricata) from the Triassic beds of Brazil, whose original description was based on 10 …

Los saurópodos titanosaurios son conocidos por mostrar una notable disparidad de tamaño
corporal, con algunos taxones famosos por acercarse al cenit del tamaño corporal de un …

A histological ground-section from a duck-billed dinosaur nestling (Hypacrosaurus
stebingeri) revealed microstructures morphologically consistent with nuclei and …

Abstract: The first pterosaur bone bed from Brazil was reported in 2014 at the outskirts of the
