The female and the calf died of exhaustion and asphyxia, respectively. Normally the mother helps the calf to breathe at the surface immediately after birth.

Note the prominent lactating mammary glands on both sides of the genital slit (top), and the placenta spread on the floor (bottom). Placentation is similar to that in cattle (epitheliochorial).Pictures taken in the Quebec provincial diagnostic laboratory, MAPAQ, Rimouski.
