Markham's frog
Markham's frog is one of three extinct New Zealand frog species, the others being the Aurora frog and Waitomo frog. Subfossil bones used to describe the species were discovered at Honeycomb Hill Cave, South Island, New Zealand, but it once occurred on both South and North Islands. It is estimated that it grew between 50–60 mm from snout to vent and it appears to have been a very robust animal.
