re: New long-necked gliding reptile
I agree with Silvio Renesto.
Interesting that Coelurosauravus was not mentioned by Fraser as the most likely
sister taxon. The neck length/torso length ratio is better than 4:10. And
sister taxa, like Icarosaurus, shortened the torso as display (think of
Chlamydosaurus) evolved into gliding.
Somewhat like Tanystropheus, Coelurosauravus has few to no chevrons and a
non-terminal naris (did the artist get it wrong?). The pelvis is close in
Like Coelurosauravus, the artist impression has the same manual and pedal digit
ratios and proportions. The limbs are similar to Coelurosauravus in length. The
teeth are presumeably likewise small and uniform, because the artist did not
show them -- unlike Tanystropheus.
Unlike Coelurosauravus, the artist provides no 'crown/shield', a terminal
naris, no deep posterior mandible. The wing pattern is more like that of
Icarosaurus, with fewer 'ribs' and following the same pattern.
In my cladistic analysis Coelurosauravus is a sister to Icarosaurus, so such a
creature is not that far out there.
But if it is related to Tanystropheus, it would be.
