Correlation coefficients between the extinction times of four mammal groups within a grid of 100 × 100 km² in Eurasia and human impact indices. (Indices include the number of human sites that are older than animal fossil age (human density), and the average nearest distance of animal fossil sites to human sites that are older than animal fossil age (human proximity distance ≦ 200 km). ‘WE’ in ‘mammal groups’ denotes western Eurasia; ‘EE’ denotes eastern Eurasia; *p < 0.05, **p < 0.01, ***p < 0.001.)

mammal groups	human proximity	human density
mammoths (WE)	0.27***	−0.3***
mammoths (EE)	0.42***	0.22***a
rhinoceroses (WE)	0.31	−0.53***
rhinoceroses (EE)	−0.17	0.69***a
horses (WE)	−0.67***a	0.13
horses (EE)	−0.36*a	0.48***a
deer (WE)	−0.26**a	−0.15
deer (EE)	−0.31**a	−0.14

^aThere is evidence of negative human impacts on the large mammals.
