After much prodding from friends and family, I decided to enter this into the "All Yesterdays" contest, put on by and
Ichthyovenator laosensis - the fish-eating hunter of Laos, known only from a single type specimen found in the Aptian age Grès supérieurs Formation. Siamamia, a Cretaceous cousin of the North American bowfin fish, is known from similarly aged rocks in the Sakon Nakhon Province of Northeastern Thailand.
I have depicted this icthyovenator as having a semi-aquatic lifestyle, cruising the Cretaceous swamps with powerful tail muscles anchored to the large neural spines along its back, hips, and tail.
