Giant "phoenix" bird lived with dinosaurs

An enormous jawbone found in Kazakhstan is further evidence that giant birds roamed - or flew above - the Earth at the same time as the dinosaurs. http://www.bbc.co.uk/news/science-environment-14466814

So if birds evolved from dinosaurs, what did this thing evolve from?

Asian 'phoenix' lived with the dinosaurs I was actually excited as I thought they found a phoenix (considering it is on UM)... but nope, it is a bird. The title is messed up... Also the bird looks like an ostrich... perhaps it didn't fly?

So if birds evolved from dinosaurs, what did this thing evolve from? Are you high or just a tad obsessed?

They lived like 65 million years ago. Well, maybe the next were related: http://en.wikipedia.org/wiki/Phorusrhacidae http://newswatch.nationalgeographic.com/2010/08/21/a_new_look_at_old_terror_birds/ There was was in France around the same time: http://www.nature.com/nature/journal/v377/n6545/abs/377110a0.html

Perhaps a predecessor of the Moa? They grew to about 12 ft. in height and weighed in at around 500 lbs... though they were flightless.... EDIT: Or a Haast's Eagle...

Well then it seems we have more brids that could carry off a human

So if birds evolved from dinosaurs, what did this thing evolve from? The theory is that birds and dinos evolved from some common ancestor.

Old news, but still: A new giant ground bird from the Upper Cretaceous of southern France Abstract New discoveries afford a much better knowledge of the large birds previously reported from the Upper Cretaceous of southern France on the basis of a single synsacrum fragment. An incomplete pelvis consisting of the synsacrum with part of the ilia is used to define a new taxon of bird, Gargantuavis philoinos, to which a femur is also referred. This bird is characterized by its very large size (comparable to that of an ostrich), a broad pelvis with an anteriorly placed acetabulum, and a short robus... [More]

The theory is that birds and dinos evolved from some common ancestor. Thank you for considering my question, unlike Blue Lizard
