How would you describe the morphology of three individual tracks of your biserial trackway that does not have a medial trail?

• Linear
• Linear, punctiform
• Linear, ovoid, crook-shaped
• Curved
• Punctiform
• Oval, linear, comma-shaped
• Circular, oval

Please note, that in trackways there is a high uncertainty when it comes to ichnotaxonomical determination. This has its reason in preservational differences (e.g. track vs undertrack; grain size of the substrate and its consistency, etc.), number of tracks (especially in underwater traces where the buoyancy may lift the tracemaker’s body and prevent some extremities to produce tracks) and of course interpretational biases. Trackways are repetitive series of individual elements. One of these elements may just be a left and a right food of a bipedal tracemaker, but might also be a series of individual tracks, e.g. six imprints produced by the extremities of an insect.
