Kurzbeschreibung des Verlags

Travel back to Late Triassic Argentina and discover Herrerasaurus, one of the most important early dinosaurs for understanding the beginning of dinosaur evolution.DINOSAUR ENCYCLOPEDIA SERIES 40 HERRERASAURUS explores Herrerasaurus ischigualastensis across 22 carefully organized topics.Its relatively long and narrow skull, sharp recurved serrated teeth, unusual lower jaw, long hind limbs, long tail, and distinctive five-digit hands provide important evidence about the anatomy of one of the earliest dinosaurs.The first three digits of the hand were well developed, while digits IV and V were strongly reduced - a particularly important feature for understanding early dinosaur hand evolution.This volume also examines questions that cannot yet be answered with certainty.How were the forelimbs used?How fast could Herrerasaurus move?Did it have scales, filament-like coverings, or another type of integument?What animals did it eat?How did it grow?What senses did it rely on?The book also explores the Late Triassic Ischigualasto Formation of San Juan Province, Argentina, including its river and floodplain environments, representative vertebrates, and the geological setting in which Herrerasaurus fossils were preserved.Its exact position on the dinosaur family tree remains debated. Different phylogenetic analyses have recovered Herrerasauria in different positions among early dinosaurs.Rather than presenting one hypothesis as settled fact, this encyclopedia distinguishes between confirmed evidence, scientific interpretation, phylogenetic hypotheses, and questions that remain unresolved.With evidence-based explanations, anatomical diagrams, and carefully designed scientific reconstructions, this volume presents both what paleontologists know about Herrerasaurus and what they are still trying to discover.Suitable for upper-elementary readers, families, dinosaur enthusiasts, and general readers interested in paleontology and early dinosaur evolution.
