Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

open access: yesThe Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Dissolution behavior of partially calcined limestone with residual CO2 in converter slag

open access: yesJournal of Materials Research and Technology, 2022
Accelerating the dissolution rate of lime in converter slag at the initial stage of steelmaking is conducive to the rapid slagging. In this work, partially calcined limestone with a core–shell structure was prepared, and the dissolution behaviors of lime,

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...
