Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

open access: yesThe Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Inventory of the Decapod Crustaceans (Crayfishes and Shrimps) of Arkansas with a Discussion of Their Habitats [PDF]

open access: yes, 1980
The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Sensitivity of coastal jet structure to coastal topography

open access: yes, 2003
Fifth Conference on Coastal Atmospheric and Oceanic Prediction and Processes, August 5-8, 2003 A low-level core of high wind speeds aligned along the U.S. West Coast, known as the coastal jet, is a persistent feature during the summer months. The seasonal preference for such a feature is a function of several conditions; warm temperatures inland, cool ...

Concepts of Design of Coastal Structures

open access: yesCoastal Engineering 1976, 1976
Certain design of the existing and proposed coastal structures for lateral loading in the United States is presently based upon the use of timber which is structurally inefficient in the elastic range. Figure 1, for example, indicates the plan of timber pile structure.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

open access: yesThe Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

ECONOMICS OF COASTAL STRUCTURES

open access: yesCoastal Engineering Proceedings, 1951
The engineer is constantly called upon to make an economic analysis of proposed engineering works. His analysis is just as trustworthy as his base information. In some cases experience and knowledge are so complete that an estimate can be accepted with assurance of great accuracy.

Coastal Structure Inspection Technologies: Investigation of Multibeam Sonars for Coastal Structure Surveys [PDF]

open access: yes, 1998
Abstract : This report discusses research conducted to investigate and develop hydrographic survey equipment for objective, detailed, and quantitative definition of the underwater shape of coastal structures. The research included development of and investigation of the Coastal Structure Acoustic Raster Scanner (CSARS) system. Although much information
