▁in ▁this ▁way ▁they ▁lose ▁some ▁mechanical ▁advantages ▁and ▁power ▁in ▁their ▁b ite ▁but ▁gain ▁speed ▁instead . ▁ ▁The ▁j aws ▁and ▁pal ates ▁have ▁a ▁battery ▁of ▁large , ▁cur ved , ▁and ▁slightly ▁ke e led ▁teeth . ▁ ▁On ▁the ▁upper ▁j aw ▁there ▁is ▁a ▁pair ▁of ▁vom er ine ▁t us ks , ▁and ▁two ▁pairs ▁of ▁pal atal ▁t us ks ▁with ▁ 5 ▁or ▁ 6 ▁smaller ▁teeth ▁between ▁each ▁of ▁the ▁pairs . ▁Each ▁pair ▁of ▁t us ks ▁has ▁a ▁de pression ▁for ▁two ▁teeth ▁on ▁each ▁side ▁of ▁the ▁j aw ▁with ▁only ▁one ▁to oth ▁present ▁at ▁a ▁time . ▁It ▁was ▁one ▁thought ▁that ▁the ▁empty ▁de pression ▁was ▁fit ▁for ▁the ▁teeth ▁of ▁the ▁lower ▁j aw ▁in ▁order ▁to ▁close ▁the ▁mouth , ▁but ▁upon ▁further ▁ins pection ▁small ▁bits ▁of ▁to oth ▁could ▁be ▁seen ▁in ▁the ▁empty ▁de press ions ▁showing ▁that ▁there ▁was ▁a ▁to oth ▁there ▁once . ▁The ▁size ▁of ▁the ▁teeth ▁var ies ▁on ▁the ▁upper ▁and ▁the ▁lower ▁j aw , ▁the ▁larger ▁teeth ▁being ▁more ▁anch ored ▁into ▁the ▁mand ible ▁than ▁the ▁smaller ▁ones ▁on ▁the ▁lower ▁j aw . ▁ ▁Pale obi ology ▁▁ ▁Based ▁only ▁on ▁the ▁size ▁of ▁the ▁sk ull , ▁the ▁full ▁body ▁size ▁of ▁L ox om ma ▁is ▁approxim ated ▁to ▁be ▁ 1 4 ▁feet ▁long , ▁although ▁it ▁is ▁hard ▁to ▁tell ▁definit ively ▁without ▁the ▁presence ▁of ▁any
