Seventy-million-year-old dinosaur footprints found near Whanganui inlet in NW Nelson; probably made by sauropods

Scientists have found 70-million-year-old dinosaur footprints in northwest Nelson.

They are the first dinosaur footprints to be recognised in New Zealand and the first evidence of dinosaurs in the South Island.

Geologist Greg Browne of GNS Science, found the prints while investigating rock and sediment formations near the Whanganui inlet. They are at six locations over an area of about 10 kilometres. At one location there are up to 20 footprints.

The depressions are roughly circular, with the largest about 60cm in diameter. Most are smaller, typically between 10 and 20cm in diameter.

Dr Browne believes the markings were made by sauropods, which were large herbivorous dinosaurs with long necks and tails and pillar-like legs. The prints were made in beach sands and were probably quickly covered and preserved by mud from subsequent tides.

?What makes this discovery special is the unique preservation of the footprints in an environment where they could easily have been destroyed by waves, tides, or wind.?

While paleontologists know that dinosaurs were present in ancient New Zealand, the record of their presence is very sketchy.

Dinosaur bones have only been found in northern Hawke’s Bay, Port Waikato, and the Chatham Islands.

Dr Browne said the footprints added a considerable amount of information about how dinosaurs moved, how fast they moved, how big they were as well as how soft the sediment was when they moved through the area.

“This discovery opens the way for further study on a range of dinosaur-related issues in New Zealand.”
