Life reconstruction of Palaeopython helveticus sp. nov. and other faunal elements of the Dielsdorf palaeoenvironment during the late middle–late Eocene. In the foreground, an adult Palaeopython helveticus sp. nov. is approaching two microchoerine primates of the genus Necrolemur. On the tree trunk, a Palaeovaranus is resting. Two alligatorine crocodylians are seen inside the water, while an indeterminate chiropteran is flying above. The two large mammals on the far side of the bank are the perissodactyl Palaeotherium magnum, while the smaller one on their left represents the perissodactyl Lophiotherium
