Title: Rich and Diverse Fossil Species Discovered in New Zealand’s Ancient Marine Channel
In a groundbreaking discovery, a recent paper published in the New Zealand Journal of Geology and Geophysics has unveiled a treasure trove of fossil species found in New Zealand. Estimated to be three million years old, these fossils were unexpectedly unearthed during excavation work for a major pipeline upgrade in Auckland.
Renowned Auckland paleontologist, Bruce Hayward, excitedly compared the find to stumbling upon gold on one’s own doorstep. Recognizing the significance of the fossil deposit, Watercare and their contractors promptly provided assistance by depositing a large amount of sand, filled with fossils, in a nearby paddock for paleontologists to meticulously sift through.
The subsequent examination of over 300,000 fossils has led to the identification of numerous species of immense importance. Several thousand specimens have been carefully archived at the Auckland Museum to record this remarkable discovery.
These invaluable fossils were deposited millions of years ago in an early version of the modern Manukau Harbour, when the world was warmer and sea levels were slightly higher. The fauna includes subtropical species that are akin to those found in the warmer waters encircling the Kermadec and Norfolk islands.
Comprising an astounding 266 different fossil species, this collection makes it the richest and most diverse fauna of its age ever discovered in New Zealand. The fossils originate from various environments that were brought together in an ancient marine channel, molded by wave action and tidal currents.
Among the rare finds are ancestral specimens of the iconic NZ flax snail, which hold the distinction of being the oldest known flax snails in the world. Other remarkable findings include whale vertebrae, a sperm whale tooth, the spine of an extinct sawshark, dental plates of eagle rays, and even teeth from great white sharks.
Adding to the significance of this discovery is its dedication to the late Dr. Alan Beu, a leading expert in molluscan fossils who had been actively involved in studying these fossils before his passing.
This exciting breakthrough sheds new light on New Zealand’s prehistoric marine ecosystems and underscores the country’s geological importance. As further research unfolds, scientists anticipate unveiling more intriguing discoveries that will contribute to our understanding of the Earth’s ancient past.
