Sauropodomorpha Huene 1932 is one of the most successful groups of dinosaurs, including the most abundant and diverse herbivorous forms with a worldwide record, extending from the late Triassic to the late Cretaceous. Sauropodomorphs comprise a diverse assemblage of early forms (traditionally called “prosauropods”) and the well-established clade Sauropoda Marsh 1878. Early sauropodomorphs were small to medium sized forms, with long necks and reduced skulls, mostly bipeds and omnivores and ...

An in-depth look at the origin and evolutionary radiation of the synapsids.About 320 million years ago a group of reptiles known as the synapsids emerged and forever changed Earth's ecological landscapes. This book discusses the origin and radiation of the synapsids from their sail-backed pelycosaur ancestor to their diverse descendants, the therapsids or mammal-like reptiles, that eventually gave rise to mammals. It further showcases the remarkable evolutionary his...

A guide to this fossil-rich area of Spain: "Likely to become a landmark reference in dinosaur ichnology." —James O. FarlowDuring the Early Cretaceous, lakes, meandering streams, and flood plains covered the region where the current foothills of Rioja now exist. Today the area is known for its wine and for the dozens of sites where footprints and trackways of dinosaurs, amphibians, and even pterosaurs can be seen.The dinosaurs that lived here 120 million years...

Easily distinguished by the horns and frills on their skulls, ceratopsians were one of the most successful of all dinosaurs. This volume presents a broad range of cutting-edge research on the functional biology, behavior, systematics, paleoecology, and paleogeography of the horned dinosaurs, and includes descriptions of newly identified species.

A comprehensive study of the Late Cretaceous, duck-billed dinosaur, featuring insights on its origins, anatomy, and more.Hadrosaurs—also known as duck-billed dinosaurs—are abundant in the fossil record. With their unique complex jaws and teeth perfectly suited to shred and chew plants, they flourished on Earth in remarkable diversity during the Late Cretaceous. So ubiquitous are their remains that we have learned more about dinosaurian paleobiology and paleoecology ...

This e-book provides a detailed review including often overlooked aspects of the human parasite Trypanosoma cruzi. There is no vaccine and infection leads to the incurable Chagas' disease, which is eventually fatal. Pathology is manifested in tissue and neuronal destruction, most commonly leading to megaesophagus, megacolon, and cardiomyopathy; characterized by a severely enlarged esophagus, colon, and heart, respectively. Each of these thirteen chapters features different aspects of the p...

Centris (Paracentris) Cameron is one of the most specious and morphologically diverse subgenera of the bee genus Centris Fabricius. These two features, along with the lack of modern taxonomic revisions make this group one of the lineages with the greatest taxonomic problems within Centridini.Partial revisions of groups of species from North and South America have been published, but none comprehensively studying all species described. In this paper...

This book deals with two lineages of solitary bees that are distributed throughout the Neotropical Region, collecting oil from plants with oil-bearing flowers, producing their reproduction.New species for science belonging to the two groups studied are described here: the subgenera Centris (Aphemisia) and C. (Schisthemisia). Additionally, diagnoses of the species already described, identification keys, a complete list of ...
