Mesozoic - History of Earth's Climate
Basically, you cannot talk about decreased or increased water levels in the world's oceans without a fixed reference point or reference level, and since both the sea basin and the land masses have constantly changed, it is obvious that you do not have such a point or level. But in any case there is a lot of evidence that a larger part of the Earth's surface was covered by sea during the Jurassic, which meant that many low-lying areas were transformed into shallow coastal areas, and at the same time the climate became more oceanic, i.e.

August 26, 2024 -
So, one thing that I hear in a lot of documentary shows (I think I even heard this one line pop up in a relatively recent series) is that during the mesozoic, the weather was on average much warmer than it is today, which fine, BUT... They sometimes even go so far as to say that there definitely was not and below freezing temperatures anywhere on Earth at any point during the entire span on the age of dinosaurs. One very recent one (as in I'm fairly sure the series was made in the last 4-5 years) even made the claim that the ice age that we had immediately prior to the rise of homosapiens was the first ever seen on Earth and that ice had never before had a chance to form on Earth...
But then there's been a lot of paleo art done of things like pachyrhinosaurus being like this thing with a great shaggy covering of downy feathers hanging out in snowy fields. Usually something pretty similar with yutyrannus.
And I get that in paleo art, the depictions are largely based on the artist's ideas of character scenes made for a cool shot rather than complete accuracy.
But I want to know... Were there snowy winters during the age of dinosaurs? Were there parts of the world that were consistently cold or temperate, or at the very least not some binary of the typical depictions of the world either being rainforest or desert?

It was warmer on average, that’s true. It was still cold enough for snow and ice in some regions, though, so Pachyrhinosaurus probably would have seen some snow. What show said the Pleistocene was our first ice age? Sure, they’re relatively rare, and the last one occurred all the way back in the Permian, but saying ice had never existed is just wrong.

It was warmer on average but differentials still existed and at the poles in particular it still got dark for months at a time and that makes it plenty cold to snow and ice up. And one study found a way to prove from fossils that at least some dinosaurs lived that far north even in the winter.

Climate Science Investigations South Florida - Temperature Over Time
During the Mesozoic era, there is no evidence of major glaciation, due in part to the large supercontinent, Pangaea, being located closer to the equatorial region of the planet. Some parts of Pangaea extended toward the South Pole but were still warm. As Pangaea split and the continents moved closer to their current positions, the climate remained warm.

There is still much debate on the actual global temperature distribution and its effects on Climate. This period is often used as a comparison to modern global warming. The Mesozoic era ends with a brief cooling, accompanied by the extinction of dinosaurs.

Since the rise of the diatoms in the Mesozoic Era, climate change and tectonism have influenced their evolution, diversity, migration, and biogeography, as niches and environments are created and destroyed (see Jordan and Stickley, 2010 for review and references).

The ‘gradualists’ consider it was prolonged and caused by climate change or volcanic activity, with the meteorite only providing the final blow. Many scientists believe that the impact of one or more meteorites was the major cause of the end-Mesozoic extinction.
