Fwd: the largest Pterosaur



Hi there,

The biggest pterosaurs are not known from complete specimens, so all
the figures you see on this subject are only estimates based on
extrapolation from smaller, more complete finds. Currently, the record
holders amongst pterosaurs (and, indeed, all volant animals) are the
giant azhdarchids, enormous pterosaurs that existed across the world in
the Cretaceous. The best known of these is Quetzalcoatlus nothropi from
the Javelina Formation of Texas. Known from a stupendously big humerus
and other fragmentary elements, the wingspan of this animal is estimated
at 10 - 11 m with a shoulder height of 2.5 m when it stood on the
ground. 

However, other azhdarchids known from even scantier material hint at
bigger animals. Arambourgiania philidelphae, a pterosaur known from a
solitary neck vertebrae and scrappy wing elements from Jordan, may have
achieved a wingspan of 11 - 13 m. However, Hatzagopteryx thambema is the
current record holder for the largest pterosaur known: with only a few
pieces of skull and a couple of scrappy limb elements, estimates for
this critter put it between 12 - 14 m across the wings.

At the risk of blowing my own trumpet, you can see for yourself how big
some of these pterosaurs got here:

Dear lists, 

I would appreciate it if someone could tell me.

What is the most largest Pterosaur?
