English: a sequence diagram of the feline machairodont Homotherium using the "shearing bite" hpythesis to wound a prey animal. i have no scanner at my disposal, so i used a samsung camera to take a picture of the drawing, created with an ultrafine sharpie and a sheet of standard printing paper. from there it was uploaded, the contrast and brightness modified to be as clear as it was on the sheet origionally, and uploaded here.
