Friday mystery object #243 answer


Last week I gave you this nightmarish looking mystery object to identify:

mystery243

There were lots of great suggestions about what it might be, with most of you in the right area of the animal kingdom with a legless critter in mind. In particular a fairly primitive type, with aglyphous or ‘groove-less’ teeth (as opposed to snakes characterised by having opsithoglyphous or ‘backward grooved’, proteroglyphous or ‘forward grooved’ and solenglyphous or ‘pipe grooved’ teeth).

There were several suggestions of Boa constrictor – specifically the right maxilla (upper jaw), but they have a straighter top to the maxilla and a differently shaped process that connects with the frontal and ectopterygoid bones (check out Udo Savalli’s snake skull anatomy page to see what those terms mean).

Anaconda was also suggested, but the anterior (front) part of  the maxilla is not squared off enough.

Nicola Newton, rachel and Alex Kleine all suggested Python, which is what I think it is. I’m not certain of the species, but it’s definitely a big one – I’m leaning towards the Reticulated Python Python reticulatus (Schneider, 1801).

Just to give you a better idea of which bone it is, here it is compared to the skull of another large Python skull from the Horniman’s collection:

and to give a better sense of scale, here it is with my (fairly large) hand for comparison:

mystery243a

My very rough estimate of the length of the animal, based on other skeletal material I’ve seen, is around 5m – that’s one snake I wouldn’t want to get on the wrong side of!
