Polar Dinosaurs

And the rain was upon the earth forty days and forty nights.
Genesis 7:12


"Polar dinosaurs refer to dinosaur fossils found within the polar
latitudes. In the Southern Hemisphere, polar latitudes would also include southeast Australia, New Zealand, and the Chatham Islands where dinosaur fossils have been found. existence of polar dinosaurs has raised at least four conundrums for the evolutionary paradigm. For instance, climate models indicate the polar latitudes would have been very cold during the Cretaceous winter, while the paleoflora and paleofauna indicate temperatures had to have been above freezing all year around:



Paleobotanical evidence clearly indicates that during much of the Cretaceous northern polar temperatures on lands surrounding the Arctic Ocean were above freezing during the polar night. … Evidence for very warm Arctic Ocean waters (15 to 20°C) has been presented by Jenkyns et al. (2004). Proxy data indicating ocean temperatures of 30°C at 60°S latitude (Bice et al., 2003) supports the idea of warm poles during much of the Cretaceous.”

Hay believes that lower topography, higher ocean levels, and greenhouse gases, including carbon dioxide and methane, would have maintained above-freezing winter temperatures. 

He also erroneously thinks that, considering the average lapse rate of the atmosphere of 6°C/km, the lower topography would have resulted in warm polar night temperatures. Even if this lapse rate could be applied, it would not have warmed the Arctic much because the air was so cold to begin with. As far as lower topography is concerned, the continental areas of North America and Eurasia are relatively low anyway. Besides, the polar night causes a temperature inversion to which the average atmospheric lapse rate would not apply. 
---Despite all the possible variables that could be applied to cause polar warmth, the cold winter temperatures depend especially on one variable: the angle of the sun, and the evolutionary model cannot do anything about that for the Cretaceous.

Cold winter temperatures are one of several other conundrums. For instance,

Q: why would dinosaurs have even lived there, considering that most scientists believe dinosaurs to have been warm-climate animals? Polar dinosaurs have unleashed much speculation on Arctic coping mechanisms.

Q: With long periods of darkness and photosynthesis cut off—and the resulting loss of vegetation—what would they have eaten?

The Creation/Flood model has the most plausible explanation for why
we find
polar dinosaurs
The most likely explanation is the dinosaurs and the paleoflora were transported northward on Flood currents during the Inundatory Stage of the Flood.
In addition, very thick sediments, well over 10 km thick, are found on the Arctic margin, indicating immense northward erosion and transport of sediment from Alaska, pointing to northward currents at times during the Flood."
