Tiktaalik is a lobe-finned fish that lived in the late Devonian period
about 375 million years ago. Its
fossils, which have
been found on Ellesmere Island in Nunavat,
Canada
show an animal that has a mix of fish-like and tetrapod-like
characteristics.
Fish-like features include gills and scales.
Tetrapod-like features include rib bones, mobile neck,
and evidence that it probably had lungs and was therefore
able to breathe in air.
Additionally, there are some features which
are intermediate between fish and tetrapods,
namely limb bones and joints which were similar
to tetrapods but ended in fish-like fins rather than toes,
and an ear region which seems intermediate between fish
and tetrapods.
Tiktaalik is thought to have lived on the bottom
of shallow waters, and perhaps even be able to emerge
from the water for short periods. It had rows of sharp
teeth, eyes on the top of its head (in a similar
position to a crocodiles),and was a predator.
