Through examining the muscle scars of femora of enough " Asilisaurus " specimens as well as histological studies, they proposed that instead of considering variations as sexual differences, they are better interpreted as individual differences.

The leg musculature of " Poposaurus " was hypothesized in a 2011 study that examined muscle scars on the bones and made inferences based on phylogenetic bracketing . 26 muscles, three ligaments, and two connective tissue structures were described.

The presence of the teeth was later questioned in a 1998 study by G . Geyer and M . Streng and cited the lack of preserved muscle scars as reason to suspect the placement of " Camya asy " in Bivalvia.

The "'pallial line "'is a mark ( a line ) on the interior of each adductor muscles the pallial line usually joins the marks known as adductor muscle scars, which are where the adductor muscles attach.

The left hindlimb is completely preserved on the main slab, and shows a slightly curved femur, a proximal muscle scar likely to represent the greater trochanter, a slender tibia and fibula, a remarkably birdlike tibiotarsus, and the four delicate toes of the foot.

The notation 2, 3a, 3b, 4a, 4b and 5a refer to the numbers assigned to individual teeth . " aa " and " pa " are the anterior and posterior muscle scars and " ppr " is the scar left by the posterior pedal retractor muscle.

These probably supported the zygapophyses all appeared to have been large and robust ( with the latter bearing many pits and edges that likely represent muscle scars ), and the basioccipital tuberosities were long; these all serve as points of attachment for various muscles of the head and neck.

The position of this line is often quite clearly visible on the inside of each valve of a bivalve shell, as a shiny line, the pallial line, which runs along a small distance in from the outer edge of each valve, usually joining the anterior adductor muscle scar to the posterior adductor muscle scar.

Also, in those bivalves with two adductor muscle scars of different sizes, the " posterior " scar will be the larger of the two and will be visible on both valves this condition is referred to as being " anisomyarian "; if the scars are of equal size, this is termed " isomyarian "; if the valve has only one muscle scar, this is termed " monomyarian ".
