It's Black Skimmer baby season so will be posting a few of those. This set of 3 is a baby skimmer cuddling up with a parent. Please check out all 3. I think the last one may be my favorite.

There's little information on ictalurids at 66 Ma. A few scrappy fossils from the Cretaceous and molecular phylogenies showing all the living species descended from a single ancestor that survived the cataclysm.

In 1993, fisherman Lyle Dyslin pulled up a rather strange catfish. It had a flat head, a flat tail, a dog-like face and almost feet-like fins. After taking a photograph, he threw the fish back into the lake. Theories on what it was range from a long extinct species to a mutation
Praearcturus gigas, a giant (>70cm) stem-scorpion from the early Devonian Britain. Frankly: I just shocked no one try to draw this based on new reconstruction.
It bears flap-like structures along the mesosoma, and could be amphibious. Than what if they can swim?

The best stuff:
* Animal reconstructions are wonderful! With rare exceptions (lizard-like scales and colors on the anomodont Suminia, which more likely had similar skin to their cousins the dicynodonts), they were great.
