Paul Scofield and amateur paleontologist Leigh Love investigate a section of the riverbank on the Waipara River, near which the Protodontopteryx fossil was found.
One of the world's oldest bird species was discovered at the same site in North Canterbury, where a monster penguin fossil was found.
Bone-toothed birds (pelagornithids), u It has been thought that the ancient family of giant seabirds in the Northern Hemisphere has evolved to the discovery of New Zealand's oldest but smallest family member.
At 62 million years old, the newly discovered Protodontopteryx ruthae is one of the oldest named bird species in the world, which lives in New Zealand shortly after the end of the dinosaurs.

The amateur paleontologist Leigh Love discovered both the penguin and the partial protodontopteryx skeleton at a distance of only a few months at the fossil site Waipara Greensand.
The bird was named after Loves wife Ruth Protodontopteryx ruthae.
Scofield said the age of the fossilized bones suggested that pelagornithids developed in the southern hemisphere when New Zealand had a tropical climate and a sea temperature of about 25 degrees Celsius.
Scientists from Australia and New Zealand have found evidence of a so-called "really gigantic parrot" among 19-million-year-old fossils.
"While this bird was relatively small, the impact was the effect Until we found this skeleton, all the really old Pelagornithids had been found in the Northern Hemisphere, and everyone thought they had developed there."
Mayr said the discovery Protodontopteryx was "really amazing and unexpected".
"The fossil is not only one of the most complete specimens of a pseudo-bird, but it also exhibits a number of unexpected skeletal features that contribute to a better understanding of the evolution of these enigmatic birds."
Later, pelagornithide species evolved to over Floating oceans with some species up to 6.4 meters in diameter.
The skeleton of Protodontopteryx indicates that it is less suitable for long-haul flights than later pelagornithids and is likely to cover much shorter distances. His short, wide pseudo teeth were probably designed for fishing. Later species had acicular pseudoteeths that were probably used to catch soft-bodied prey such as squid.
The last pelagornithidic species died out 2.5 million years ago, just before modern humans developed important scientific discoveries for love in recent years. In 2014, he made headlines when a fossil he found was recognized as belonging to an unknown group of flying seabirds and named Australornis lovei.
The following year, Love discovered the world's oldest tropicbird fossil, which also revealed the true origin of a bird. Some of the discoveries, including the Protodontopteryx fossil, will be displayed later this year at the Canterbury Museum in an exhibit on ancient New Zealand ,
