Who knew
Wikipedia could be so frustrating. All it took was one line and now my whole Saturday has become a giant side project. Granted on with very cool results, but still.
The
announcement of a
Palaeo Art competition in Europe with some pretty hefty prizes had me thinking of submitting a 3D piece or two into it. As one of the criteria the judges would smile on favourable are illustrations of
Portuguese species I decided to apply try and use my
kung fu Mosasaurs.
Which is where
Wikipedia came in. In my efforts to find out if there were any
Portuguese Mosasaurs (which I couldn't confirm or deny... I'm suspecting not, but does anyone know for sure?) I hit a sentence that really pissed me off.
Many of the 'dinosaur' remains found on New Zealand, a volcanic island chain that was never connected to any of the continents, are actually mosasaurs and plesiosaurs, another group of Mesozoic predatory marine reptiles.
You'll note the highlighted and
italicized section. What they were saying about most Kiwi
Mezesoic fossils being marine reptiles is completely true. However the author thought they were being clever by hypothesising why. They'd heard New Zealand was volcanic, and as it was an island it must be like say
Hawaii. Makes sense right? Sure, except they're completely WRONG!
Now I'll admit I on occasion try to connect dots like this myself, but typically I'll have tried to find the answer first if I'm putting it up on the web. This person clearly didn't bother to look it up at all!
If they had they'd have found out about this...
The thing is New Zealand was very MUCH attached to the other continents before it became a
separate island "chain". In fact it was connected to two of them! Australia and Antarctica. When it originally
separated from them it was a continent itself,
Zealandia as geologists call it, which was half the size of Australia!
However due to
Zealandia's relative thin continental crust it sank shortly after
separation, and most of it sank with the exception of what would become modern New Zealand and the few other surrounding islands.
Now I was so
infuriated by the
Mosasaur sentence I actually went into
Wikipedia and edited it. So you won't find that version. I was gracious enough to leave the original sentence minus the offending aside (which wasn't needed anyway). Now that I've seen how easy it is to change things on Wiki I'm going to be a lot more doubtful about stuff I read on there!
However I was left with both a residual sting of
annoyance, and a need to show off my knowledge of this apparently specialized geologic history. Especially given no one had ever illustrated it before!
I'd been wanting to learn how to do this anyway.
I was going to create a realistic continent!
The only reference I had of
Zealandia was this topographic map.
If you weren't able to make out which parts were
Zealandia here it is outlined.
Through some
photoshopping of a high resolution globe of the modern Earth I was able to steal bits and pieces of various modern continents to make a pretty convincing ancient
Zealandia. The great thing is though we know roughly what its outline was, no one can tell me I got the details wrong. The only thing we know is that it was a very flat place, and that modern New
Zealand's mountains are a pretty recent geologic event.
As this creating land from "nothing" technique I'd thought of a few months ago (but never tried) worked in the first go I decided to take some more time to throw a few
comparative pics together.
I was going to get around to trying this anyway, just hadn't planned on today, as
Traumador will soon be going into more New Zealand
palaeo stuff. With a possible "trip" of sorts where he might explore it closer...
Let me know what you think.
