▁by ▁a ▁tort o ise . ▁This ▁is ▁now ▁known ▁to ▁be ▁incorrect , ▁as ▁tort o ises ▁did ▁not ▁evol ve ▁until ▁much ▁later . ▁It ▁was ▁first ▁found ▁in ▁Corn cock le ▁Qu ar ry ▁in ▁Dum f ries , ▁Scotland . ▁ ▁In ▁ich n ology , ▁foot print s ▁and ▁other ▁traces ▁are ▁given ▁a ▁genus ▁and ▁species ▁name , ▁the ▁ich n ogen us ▁and ▁ich nos pecies , ▁that ▁is ▁based ▁on ▁the ▁shape ▁of ▁the ▁print . ▁However , ▁it ▁is ▁almost ▁impossible ▁to ▁match ▁a ▁track mark ▁to ▁the ▁animal ▁that ▁made ▁it . ▁Ch el ich n us ▁has ▁been ▁argued ▁to ▁belong ▁to ▁either ▁a ▁ther aps id , ▁or ▁a ▁re pt ile . ▁It ▁has ▁sometimes ▁mistaken ly ▁been ▁referred ▁to ▁as ▁a ▁din osa ur ▁foot print ▁by ▁the ▁media ▁and ▁public , ▁but ▁it ▁is ▁not , ▁as ▁din osa urs ▁did ▁not ▁exist ▁at ▁this ▁time . ▁ ▁Description ▁The ▁fore ▁and ▁h ind ▁foot ▁are ▁both ▁rounded ▁and ▁nearly ▁equal ▁in ▁size , ▁but ▁the ▁fore foot ▁is ▁slightly ▁smaller , ▁and ▁the ▁fore ▁and ▁h ind ▁foot print s ▁are ▁placed ▁closely ▁together . ▁Both ▁have ▁five ▁digits ▁though ▁three ▁to ▁four ▁digits ▁are ▁more ▁commonly ▁seen ▁due ▁to ▁poor ▁pres ervation . ▁Dig its ▁are ▁usually ▁separated ▁from ▁the ▁sole . ▁The ▁inner ▁digits ▁are ▁directed ▁for wards , ▁while ▁the ▁outer most ▁digit ▁is ▁direct ▁more ▁to ▁the ▁side . ▁ ▁See ▁also ▁▁▁
