Middle Jurassic Radiolarians from the Western Pacific
Middle Jurassic radiolarians have been recovered from the western Pacific for the first time. The oldest faunas are assigned to the middle and upper Tricolocapsa conexa Zone, indicating a Bathonian/Callovian age. The faunas contain more than 30 species and are characterized by an abundance of small nassellarians with a constricted distal end. The faunas compare well with Tethyan faunas, and are...
متن کاملMiddle Cambrian Arthropods from Utah
The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important new paleontological material continues to be uncovered from these strata. New specimens of anomalocaridids include the largest and smallest near complete examples yet reported from Utah. New material of stem group arthropods inclu...
متن کاملExceptionally Preserved Jellyfishes from the Middle Cambrian
Cnidarians represent an early diverging animal group and thus insight into their origin and diversification is key to understanding metazoan evolution. Further, cnidarian jellyfish comprise an important component of modern marine planktonic ecosystems. Here we report on exceptionally preserved cnidarian jellyfish fossils from the Middle Cambrian (approximately 505 million years old) Marjum Form...
متن کاملMicro CT and Micro MR imaging of 3D architecture of animal skeleton.
Quantitative assessment of three-dimensional (3D) trabecular structural characteristics may improve our ability to understand the pathophysiology of osteoporosis, to test the efficacy of pharmaceutical intervention, and to estimate bone biomechanical properties. Considerable progress has been made in advanced imaging techniques for noninvasive and/or nondestructive assessment of 3D trabecular s...
متن کاملMicro-CT analysis of the rodent jaw bone micro-architecture: A systematic review
INTRODUCTION Knowledge about macro- and micro-structural characteristics may improve in vivo estimation of the quality and quantity of regenerated bone tissue. For this reason, micro-CT imaging has been applied to evaluate alveolar bone remodelling, alterations of periodontal ligament thickness and cortical and trabecular bone changes in rodent jaw bones. In this paper, we provide a systematic ...
