Sentences with phrase «skeletal elements»

Coral calcification is a process of skeletal elements extension and is accompanied by the development of the coral's tissues.

These results suggest that one of the key genetic events during the fin - to - limb evolution was a shift of the balance of the anterior and posterior fields (a «posteriorisation») and loss of anterior skeletal elements.

The remarkable specimen — which includes nine skeletal elements from one individual, including the thoracic vertebrae and the femoral bones — is being heralded as the «best preserved hesperornithiform material from Asia» and to be «the first report of the hesperorinthiforms from the eastern margin of the Eurasian Continent.»

«We are quite sure that the juvenile - only placoderm assemblage is not the result of sorting of small material by water currents because there are larger skeletal elements of other kinds of fish.

We used different symbols for estimations derived from footprints vs. skeletal elements, namely femurs.

In order to contextualise the australopithecine and early Homo stature estimates and range of variability obtained from the footprints within a broader picture (Figure 12), and to compare them with a larger sample, we extended our analysis to consistent data based on skeletal elements, namely femurs (see Materials and methods for details).

The sequentially - forming skeletal elements act as a single developmental module, but sizes of individual bones within the module can vary.

Given the incomplete nature of this rib and the lack of associated skeletal elements, we resist commenting on the health effects the tumor had on the individual.

Thus, the preservation of primary soft tissues and biomolecules is not limited to large - sized bones buried in fluvial sandstone environments, but also occurs in relatively small - sized skeletal elements deposited in marine sediments.

When the researchers experimentally «posteriorised» pectoral fin buds of catsharks, the fins lost anterior skeletal elements, and showed a single bone connected to the pectoral girdle, as seen in fossil Tiktaalik pectoral fins.

For the past few years, the research has focused on predictability in size proportions of skeletal elements that form sequentially — for example, molar teeth and phalanges (finger and toe bones).

«The really interesting thing to me was we had one skeletal element — a femur — where those etched bone gauges looked like they were spiraling down the surface, almost like a candy cane,» she said.

Both skeletal elements were scanned using a Nikon Metrology (X-Tek) HMXST225 MicroCT system at the Center for Nanoscale Systems at Harvard University.

«Teeth tend to fossilize and preserve better than most of the skeletal elements,» Grossnickle says, and are the most numerous type of fossil for early mammals.
