Live birth in a 47-million-year-old snake.

Die Naturwissenschaften - 5 Nov 2022

Chuliver Mariana, Scanferla Agustín, Smith Krister T

Abstract excerpt

Viviparity is a widespread reproductive trait in snakes, although fossil evidence bearing on its evolution is extremely sparse. Here, we report an exceptional specimen of the minute booid snake Messelophis variatus recovered in the paleolake of the Messel Formation (early-middle Eocene, Germany). This gravid female contains at least two embryos located in the posterior third of the trunk region. The morphology,...
