Madtsoia is an extinct genus of madtsoiid snakes. It is known from the Eocene of Argentina (M. bai), [1] the Paleocene of Brazil (M. camposi), [2] the Late Cretaceous ( Maastrichtian) of India (M. pisdurensis), [1] and the Late Cretaceous ( Maastrichtian) of Madagascar (M. madagascariensis). [3] The type species (M. bai) was the largest with an estimated length of 9–10 m (30–33 ft), [4] [5] and the other three species were smaller. [3] [2] [1] A 5.1 m (17 ft) long M. madagascariensis would have weighed 50 kg (110 lb), but an isolated specimen suggests that this species reached 8 m (26 ft) in maximum length. [3]
| Species | Length |
|---|---|
| M. bai | 9–10 m (30–33 ft) [4] [5] |
| M. camposi | 5–6 m (16–20 ft) [2] |
| M. madagascariensis | 5.1–8 m (17–26 ft) [3] |
| M. pisdurensis | 5 m (16 ft) [1] |
