Indeed, formerly planorbids were thought to have dextral shells, and so species of this family were figured as if they had dextral shells.
32.
The Walker Lane deformation belt accommodates nearly 12 mm / yr of dextral shear between the Sierra Nevada-Great Valley Block and North America.
33.
The shells of this species appear to be dextral in coiling, but as is the case in all planorbids, the shell is actually sinistral.
34.
On left-laterally sheared, sigmoidal porphyroblasts of biotite dextral shear bands are superimposed on; additionally retrograde chlorite formed in these late shear bands.
35.
2 ) Fault movement : components of normal, reverse, sinistral ( left-lateral ) and dextral ( right-lateral ) are resolved.
36.
It was also due to reverse faulting on a northnortheast-dipping plane, although with a significant dextral ( right lateral ) strike-slip component.
37.
The more common form of this shell is known as " left-turning " in a religious context, although scientists would call it " dextral ".
38.
The shells of species in this genus appear to be dextral in coiling, but as is the case in all planorbids, the shell is actually sinistral.
39.
The diameter of the teleoconch increases rapidly, the result being a shell that strongly resembles " Planorbarius " ( but, of course, dextral ).
40.
Although it is now understood that these species are sinistral in shell coiling, disk-like Planorbid shells are often still shown in illustrations oriented as if they were dextral.
