A Nomenclature for Vertebral Fossae in Sauropods and Other Saurischian Dinosaurs
BACKGROUND The axial skeleton of extinct saurischian dinosaurs (i.e., theropods, sauropodomorphs), like living birds, was pneumatized by epithelial outpocketings of the respiratory system. Pneumatic signatures in the vertebral column of fossil saurischians include complex branching chambers within the bone (internal pneumaticity) and large chambers visible externally that are bounded by neural ...
متن کاملconjugated linoleic acids, amino acid profile and other characteristics of meat produced under identical condition from two iranian fat tailed breeds of lamb
گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
The energetics of low browsing in sauropods.
It has recently been argued that the probable high cost of travel for sauropod dinosaurs would have made exploiting high forage energetically attractive, if this reduced the need to travel between food patches. This argument was supported by simple calculations. Here, we take a similar approach to evaluate the energetics of foraging close to the ground. We predict that small extensions of the n...
متن کاملDating divergence of Polystigma and other Sordariomycetes
Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...
متن کاملSauropod dinosaur research: a historical review Geological Society, London, Special Publications
In the 169 years since Owen named a tooth as Cardiodon, the study of sauropod dinosaurs has gone through several distinct periods. In the early years, a sequence of descriptions of isolated skeletal elements gave rise to a gradually emerging understanding of the animals that would later be known as sauropods. The second phase began in 1871 with Phillips’s description of Cetiosaurus oxoniensis, ...
