Sorry needed to trim some words ...

 

You may have read that a Central Otago man found Moa foot prints on a riverbed (yes, under water) made of clay ...

 

How is it possible to have footprints on clay under water for 10,000 years?

 

Someone please explain!

The clay turned to rock, as can happen over time, and the river turned up later?

They were buried under a bank, that got washed away after a flood last year, so have only been exposed for a little while.

The theory was that they were covered by a softer (clay?) and a recent storm/flood washed that away, exposing the prints in the harder clay below.

Batman: How is it possible to have footprints on clay under water for 10,000 years?

The footprints were covered by a different layer very very soon after they were made by the moa.

Another example: human footprints on the island next to Rangitoto. Covered by an ash layer from the most recent eruption. Costal erosion washed away the softer top layer and they were found by another human 600 years later.

Pretty cool this is getting publicity because these examples are likely to be common if more people look into it and learn to recognise them in context. That guy that reported until successful was actually really on to it and knew there was an excellent chance this was the real thing if not for certain.

I understand about 10,000 years ago the sea level was about 150 metres lower (approx) than now - mainly because much of the water was taking a holiday on land in the form of ice.


If one puts it another way, said Moa was probably quite a few kilometres inland.

The stuff that covers them is called sediment - it can be washed away over time.

Sedimentation plays a big role in fossils like this. *And the footprint(s) could have been printed long before the place was under water, as it was pointed out before.

 

They may have been made on a warm season, thus drying the mud faster. And the mud doesn't have to be very soft as Moas weigh 200kg. Which leads back to the *.

According to CAD there are no such things as fossils and Dinosaurs

Where do we get 10,000 years from, I doubt there has been any dating done on them yet.

 

 

 

Moa have not been extinct for THAT long in the scheme of things, a few hundred years is all that separates us from the (last of) Moa.

 

 

 

In any case, moa walks in clay, clay gets covered by various non-clay sediment quickly, prints are preserved, some couple hundred years later silt is washed away, prints are revealed.

I really wouldn't put too much stock into the dates bandied about by journalists who have probably half understood a quote.

 

I'm not a palaeontologist, but a quick google found this paper from 1991 which had the oldest specimen known at that time to be 2.5m years.

 

"There is still no significant record of the presumed long history (probably more than 20 million years, and perhaps more than 80 million years) of moas in New Zealand. "

 

And teara currently says "Only a few moa fossils up to 2 million years old have been found."

 

So if "3-4 million years" were accurate, then that would make this find even more exceptional (while obviously not a fossil it would be direct evidence older than any known fossil record of the species).

There's this from 2010, arguing that moa may have been around 19 - 16 million years ago.:

The 10,000 years likely came from the fact that the moa habitat didnt exist before then.
