We want to explore braincases
if possible, because they are exceptionally rich sources of anatomical information.
It has lots of sinuses in the braincase
like those of modern crocs," said Sankar Chatterjee, curator of paleontology at the Museum of Texas Tech, who also worked on the project.
Three age classes were assigned on the basis of ventral braincase
suture closures between the basioccipital and basisphenoid, and between the basisphenoid and presphenoid (Figure 2).
In females, the anterior zygomatic breadth, followed in order of importance by the middle zygomatic breadth, length of braincase
and length of nasals were the best discriminators of age.
Scientists who uncovered the ancient braincase
and partial upper jaw say that this evidence, combined with prior fossils, indicates that two Homo species lived simultaneously in eastern Africa from about 1.
Greatest width of braincase
measured perpendicular to long axis of skull between posterior margins of zygomatic arches.
When Alan Pradel of the MusE[umlaut]um National d'Histoire Naturelle in Paris CAT scanned the 300-million-year-old fossilized iniopterygian from Kansas, he and his colleagues saw a symmetrical blob nestled within the braincase
With proper medication and the installation of shunts to drain fluid from the braincase
, however, some individuals live 20 years or more.
Two-way ANOVAs (Table 3) with three randomly repeated measurements nested within each character corroborated MANOVA results and revealed highly significant interactions for all but four characters (width of maxilla, width of zygomatic arch, breadth of braincase
, and length of maxillary toothrow).
Washington, Jan 15 (ANI): A team of scientists has said that the earliest known braincase
of a shark-like fish has shown that some assumptions about the early evolution of vertebrates are "completely wrong.
They've compared computerized braincase
reproductions for Flo, 9 people with microcephaly and growth retardation, and 10 regular-size adults.
Many studies of previously described Archaeopteryx fossils, especially cranial scans that depict the creature's braincase
and inner ear (SN: 8/7/04, p.
As the arterial canal system of the palate and braincase
is of particular importance for defining the taxonomic position of turtles, a detailed taxonomic analysis is impossible at this time.
For body weight and many skull measurements, including braincase
size and facial width, individuals within each sex usually differ far more from each other than average members of opposite sexes do, he argues.
275), took computed tomography scans of the braincase
of a female skull from the island site.
