Peruvian deep-sea sediments : evidence for continental accretion

Creator:

Rosato, Victor Joseph

Abstract:

In order to determine whether the sediments found on the landward wall of the Peru Trench are accreted Nazca Plate sediments, the clay mineralogy and organic carbon contents of 52 surface samples were submitted to factor analysis. Q-mode factor analysis resolved the data from the Nazca Plate and Peru continental...

New insights into the biology of theropod dinosaurs

Creator:

Quick, Devon E.

Abstract:

There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...

Phylogeny and zoogeography of glyptocephalines (Pisces: Pleuronectidae)

Creator:

Chiu, Tai-sheng

Abstract:

Hypotheses of phylogenetic and historical zoogeographic relationships of glyptocephalines (Glyptocephalus cynoglossus, G. zachirus, G. stelleri, Microstomus kitt, H. pacificus, H. achne, Embassichthys bathybius, and Tanakius kitaharae) were constructed based on comparative anatomy and external morphology. The phylogenetic approach was cladistic and character polarity was determined by using out-group comparison. One...
