Genesis 1:29
"A recent study of dinosaur sizes claims to break Bergmann’s rule. Bergmann’s rule was named after biologist Carl Bergmann, who in 1847 noticed that warm-blooded animals tended to be larger in cold climates compared to the same animal in a warm climate. Larger body mass tends to help an animal retain more heat, helping animals survive in the cold..jpg)
“The fossil record provides a window into completely different ecosystems and climate conditions, allowing us to assess the applicability of these ecological rules in a whole new way,” said Jacob Gardner, a co-author of the new paper.
Led by scientists from the University of Alaska, the team studied 339 dinosaurs and 62 fossil mammals, placing them at perceived paleolatitudes and under assumed climates at the time of burial. Some of the dinosaur fossils studied were found in rocks in northernmost Alaska, in contrast to an earlier study that claimed they lived near the North Pole (about 80°–85° north latitude).

Publishing in Nature Communications, the evolutionary scientists found no compelling evidence to suggest dinosaurs and fossil mammals followed Bergmann’s rule.
However, the group also studied extant birds and mammals. Here, they found climatic temperatures did indeed have a small effect on body size, following Bergmann’s rule as expected.
Q: Is this new study sufficient grounds to throw out a 150-year-old biologic rule like the study’s scientists suggest?

A: The answer is no because their results are based on faulty assumptions, making it unlikely they conducted a valid test.
They make at least three unverifiable assumptions:
1. The science team assumes there was no global Flood. Conventional scientists disregard the historical accuracy of the book of Genesis and any reference to a catastrophic global Flood. It was the Flood that buried the dinosaurs and mammals outside the Ark, possibly moving them from their original locations.
2. They assume dinosaurs were warm-blooded. There are a lot of published reports that indicate dinosaurs were cold-blooded. Cold-blooded dinosaurs likely could not have thrived in extreme cold climates or north of the Arctic Circle as claimed.
3. They assume dinosaurs and mammals lived in high latitudes millions of years ago and were found as fossils near where they lived. Dinosaurs found in supposedly polar climates have baffled conventional paleontologists due to the cold conditions they would have faced and the long periods of darkness. Conventional reconstructions place the Alaskan dinosaurs in about 120 days of total darkness each year, making it difficult for any dinosaur to survive.

megasequences and sedimentary rocks across multiple continents, using actual rock data to reconstruct the pre-Flood land masses and their environments. It resulted in a pre-Flood world that resembled Pangaea and was centered at the equator. In fact, nearly all land was at latitudes of less than 45° north or south of the equator.
Our reconstruction places the dinosaurs in Alaska at about 35°–40° north in the pre-Flood world—not at 80°–85° where researchers placed them. This provides a much more moderate climate where dinosaurs could have thrived.
Because dinosaurs were most likely cold-blooded and never lived at extreme northern latitudes, the evolutionary scientists failed to properly test Bergmann’s rule. Their assumed paleotemperatures are simply erroneous assumptions, invalidating their findings.

Most of the pre-Flood world was likely warm and tropical to subtropical based on the fossils we find globally.
This is why they found no correlation of size to paleotemperature in dinosaurs or mammals. The temperature likely didn’t vary enough to show any body size effect until after the Flood during the Ice Age.
