Did not a young biologist working in the desert in Egypty recently discover that crocodiles actually survive desert droughts by crawling underground waiting for the rainy-season?

Do alligators live in Alaska or Antarctica now or even close to either region? Did they even make it as far north as Kansas? No they did not because they cannot survive even that much cold. Alaska is frozen rock solid many feet down for 6 unending months. Antarctica is even worse. Even a burrow just would not do it even if they are hibernating. Why can't scientists just figure out that we have sudden massive crustal shifts when the poles switch polarity. The magnetic iron core of the planet shifts polarity and abruptly switches direction just like any other electromagnetic motor. After the continental floods clearly described in many ancient stories, the massive earthquakes and hurricane winds for about 7 days we end up with about a 30 degree shift usually. Other things described in ancient times also are seen then such as the illusion of the stars falling and major aurora displays unlike anything seen in recent human history causing the planetwide squatting man images in many ancient petroglyphs. Look it up on google. Recent changes in recent ages have had the North pole at the Yukon, off Norway, near the Hudson and now in the middle of the Arctic. The Arctic shift was particularly devastating causing sea levels to cover many of our important cities under a couple hundred feet of ocean. Why are there tropical fern fossils in Antarctica and the arctic? Why did dinosaurs have a massive population in Northern Alaska, a region now very harsh even for creatures that could also survive on Hoth if they had too? Because those regions used to be much warmer even tropical. When the north pole was off Norway it is easy to see Alaska was much warmer. The dinosaurs were in a much older age. Who knows where the pole was then but since there is glacial evidence even in Madagascar it appears the current north and south pole used to be much warmer. That just sounds retarded.

This makes no sense - I suspect a typo. O. cubicularis was most likely not living in both Montana and south-east Australia. That's an awfully widespread species, unless it could build boats as well as dig burrows. It would make more sense if it was a species _similar to_ O. cubicularis, for instance an Australian hypsilophodontid like Leaellynasaura amicagraphica. In fact in the article in Cosmos the guy who discovered the burrows in Montana and Australia remarks that they were probably made by different species. None-the-less, it's amazing how much more we know about dinosaur behaviour than we did when I was a kid. I remember books saying that dinosaurs didn't burrow or climb trees. It's nifty how we learn new stuff! “Scientists aren‘t sure which dinosaur species made the newly discovered burrows, but they suspect that the Australian tunnel also was once home to Oryctodromeus cubicularis.”
