    There has been a long standing debate on the origin of snakes.

    Some have thought that they came from smaller, burrowing lizards while others advocated an origin from within a group of larger lizards.

    Well a new transitional snake fossil may have answered the question. It still maintains many lizard like features which points the way towards the right basal group.

    Skull of the large non-macrostomatan snake Yurlunggur from the Australian Oligo-Miocene, Scanlon, Nature 439, 839-842 (16 February 2006)

    Abstract

    Some selected quotes from the paper.

    And for a less complicated look, a journalistic view.

    Interesting. Goannas are those big toothy lizards that Steve Irwin is always throwing himself upon in the Australian deserts. Better him than me! :D
