It’s not usually New Zealanders admit Australia is onto a superb factor. Our long-running trans-Tasman rivalry often revolves round accusing Australians of stealing nationwide cultural icons like Phar Lap, Pavlova or Crowded House.
But I’ve to confess that relating to championing palaeontology (the examine of fossils and what they’ll educate us about our organic heritage), the Australians have a superb factor going.
Taking an concept that originated in America, many Australian states in current a long time have began adopting fossil emblems (alongside animal, floral, marine and mineral ones) that epitomise the pure historical past of every area.
In flip, these emblems may also help promote fossil tourism, academic outreach and consciousness of the necessity for fossil safety methods.
Western Australia selected the 380 million-year-old Devonian fish Mcnamaraspis kaprios, whereas New South Wales picked a equally aged fish, Mandageria fairfaxi. South Australia adopted the 550 million-year-old Spriggina floundersi from the daybreak of complicated life – the primary animal within the fossil document whose left and proper sides mirrored one another, like ours do immediately.
The Australian Capital Territory picked the 545 million-year-old brachiopod Atrypa duntroonensis, whereas a public vote in Victoria selected the 125 million-year-old large amphibian Koolasuchus cleelandi. Queensland is at present holding a public vote to choose an emblem from 12 candidates that embrace dinosaurs, large marine reptiles, an amphibian, a crocodile, a monotreme, a plant and a sea lily.

Aotearoa’s wealthy fossil document
Aotearoa New Zealand additionally has a wealthy fossil document that palaeontologists have used to unlock the evolution of our taonga (treasured) species and their distinctive whakapapa (lineage), in some circumstances stretching again tens to tons of of tens of millions of years.
In spite of this, there’s a definite shortfall in palaeontological experience and funding, which is affecting our potential to check and shield the native fossil document.

Nonetheless, New Zealand’s fossils have captured the general public creativeness, such because the not too long ago found 16-19 million-year-old large Catriona’s shelduck (Miotadorna catrionae) from St Bathans. Fossils may also encourage future generations by way of interactive museum shows, outreach and volunteering on fossil digs.

Fossil tourism
Emblems may also assist educate us in regards to the plight and significance of fossils. Newly uncovered websites aren’t being excavated by consultants, whereas different websites are eroding earlier than our eyes. The potential info these websites maintain is misplaced.

Fossil tourism may be developed at Foulden Maar, a 23 million-year-old lake deposit close to Middlemarch in Central Otago, which the general public fought to venture from mining. It might home a museum and analysis amenities, and provide alternatives for folks to gather fossils for themselves (as occurs at Kronosaurus Korner in Queensland) or volunteer on digs (as they’ll on the Australian Age of Dinosaurs).

Time to decide on
So, what ought to New Zealanders select for his or her fossil emblem? Should we choose one thing flashy just like the pouakai/Haast’s eagle (Aquila moorei) whose ancestor, the smallest eagle on this planet, arrived in Aotearoa solely about 2.5 million years in the past and quickly advanced into the world’s largest?

What in regards to the 75 million-year-old plesiosaur Kaiwhekea katiki or the shark-toothed dolphin that seize my kids’s consideration?
We might agree that dimension does matter and select the 55-60 million-year-old large Bice penguin (Kumimanu biceae) or moa nunui/South Island large moa (Dinornis robustus). At the opposite finish of the dimensions, how in regards to the smallest fossils like 505 million-year-old trilobites, a few of our oldest fossils?
Should we think about historic worth, like the primary theropod dinosaur or one of many mosasaurs (comparable to Prognathodon overtoni) that pioneering fossil hunter Joan Wiffen found? Or ought to scientific worth prevail, just like the residing pūpū whakarongotaua/flax snail (Placostylus ambagiosus), whose ample fossil shells are instructing us loads in regards to the impacts of local weather change and human settlement?

I’m forming a committee of palaeontologists from throughout New Zealand to determine on a shortlist to place to a public vote.
