How we made our discovery

 Various other titan penguins vital during that time possessed much shorter lower legs such as Kupoupou, as well as their higher mass potentially enabled all of them towards forage also much further in the aquatic world.


Exactly just what creates Kupoupou distinct is actually that it is the earliest types understood towards look like lifestyle penguins in each dimension as well as leg percentages.


In 2003, Monash College Partner Teacher Jeffrey Stilwell found a selection of fossils on seaside systems at Chatham Isle, a landmass 800km eastern of Brand-brand new Zealand's Southern Isle.


A selection of fossils were actually acquired throughout expeditions over the following a number of years, varying coming from separated bones towards partial skeletons enclosed within difficult shake. A few of this product shown up towards come from long-extinct penguins.


Subjected as well as separated bones might be examined straight. Nevertheless, for bones of solitary people bordered through difficult shake, CT checking was actually needed towards practically expose exactly just what lay within.


Utilizing these techniques, our team had the ability to determine a minimum of 2 types of old penguin coming from Chatham Isle.



The recently called types, Kupoupou stilwelli, was actually stood for through several specimens including various wing as well as leg aspects. "Kupoupou" implies diving bird in Te Re Moriori, while "stilwelli" honours Stilwell, that arranged as well as led the celebrations associated with the fossil compilations.

Through today's requirements Kupoupou was actually big (although most probably certainly not surpassing one metre). That stated, it was actually definitely dwarfed through numerous various other fossil penguins coming from throughout the whole fossil document, along with the earliest being actually about the exact very same grow older of Kupoupou as well as the youngest lifestyle around 25-million-years back.

How we made our discovery

Nevertheless, since our team don't have actually the complete skeletal system for Kupoupou, as well as since penguin fossils are actually frequently of various percentages towards the bones of lifestyle penguins, precise dimension approximates for these old birds should be actually taken along with care.


Various other bones exposed Kupoupou resided together with a minimum of another penguin on Chatham Isle, which is actually somewhat bigger as well as much a lot extra durable. Nevertheless, these fossils weren't called as a brand-new types since the skeletal system was actually as well insufficient.
