Pachyrhachis problematicus is one of the oldest known snakes. It was a metre long seafaring reptile that, unlike its modern cousins, had small but fully formed hind-limbs, remnants of it's fully-limbed, terrestrial ancestry.

And an interesting name, too.... What was the problem, I wonder? Classifying it?
Lovely painting by the way. Your whole gallery is fantastic.
When Pachyrhachis was first described in the late 1970s (based only on the skull and anterior part of the body)it was difficult to classify hence the "problematicus" name. The author (Haas) tentatively decided that it was a long-bodied varanoid lizard, unrelated to true snakes.
It wasn't until 1997 that it was determined (by Caldwell & Lee) to be a primitive snake with vestigial back limbs.
Thanks for the info!
