I actually really like the visual aid of placing the animal in question behind or slightly above the narrator, usually comparing the size next to a currently living relative is a hit or miss since some folks may not be familiar with the animal in the first place. I do like that PBS Eons uses the presenters as scale to really drive the sense of mass home, it's surprising that more nature channels don't do that. Also, something about the person moving next to the example is more impactful then an image next to an image. (We see you editors, we love you too) Also, where did she get that shirt? I love it!

ichthyosaurs are one of evolutions success stories. They existed from the early triassic 250 million years ago to the late cretaceous 90 million years ago. They diversified in to many niches in the ocean that cetaceans are filling today. They revolutionized the seas for ever. There are Ichthyosaurs similar to Shonisaurus believed to have reaches sizes comparable to that of blue whales.

Ichthyosaurs even held out much better against competition than previously thought (then again, this seems to be the rule rather than the exception in supposed cases of group-level displacement). They actually had one last wave of diversification (including into apex predator niches) in the Early Cretaceous before being wiped out by the Cenomanian-Turonian Boundary Event. It’s only after this that mosasaurs become fully aquatic and high successful, indicating that ichthyosaurs (and the pliosaurid plesiosaurs) were preventing them from taking over beforehand.

With the cold blooded lizards, the laws of scale make gigantism very helpful: The length growing linearly, the surface grows with the length squared and the volume with length cubed, the volume over surface ratio keeps growing. In cold environments like the sea this helps the ability of a predator to move more quickly and to maintain heat it collected when dwelling near the surface in regions warmed by sunlight for longer and maintains the heat of its own metabolism generated when active. So it's not a surprise bigger ichtyosaurs were a success.

@@rafikioftatooine5268 It mainly is the maths. Lenth: L Area L² Volume: L³ If you double the length of a body, its surface area gets four times a big, its volume eight times as much as it was before. The loss of heat from a body is proportional with its surface area. The bigger a body is, the smaller the ratio of volume over area gets, so the heat loss gets less. Muscles produce warmth when working, also with cold blooded animals. A big cold blooded being will thus have some of the advantages of warm bloodedness by just becoming very big.

Tool use in the water is quite difficult. Probably we wouldn’t find any signs of tool use and play in cetaceans if they were all extinct by now. We would say just massive animals adapted for predation. Probably in life they had some intelligence, but we don’t know. Their way of growth was different though. Mammals nurse their young with milk. Probably those animals were going to be able to eat immediately. So no adolescence in the same way as in mammals.

I think breathing air with a high O2 content may have something to do with that. Note, some sharks can get really huge such as Megalodon, and the extant whale shark. The ray-finned Leedsichtis problematicus is estimated to have been even larger, at least 17 m.

Actually, it's quite wonderful to imagin what wonderful forms of life will come around after we finish making our upheaval in geological timescale. Even Premian-Triassic wasn't as destructive as we are. I guess humans can only wonder what mind-blownig creatures will emerge from our failures in a few million years. I personally root for cephalopods to become mangrove dwellers and then full-blown arboreals. The only way to save Earth from dolphin dominance xD

@@_rosmarino many animals return to the sea following mass extinction events due to an abundance of prey not found on land. By hunting in shallow waters for a long time they would eventually evolve more aquatic adaptions, which leads to deeper water hunting and more adaptions over time. Think of whales and cetaceans- the most likely reason is that the earliest whales, back when they were mammals, found an abundance of untapped prey in the seas which encouraged them back to the water. Over time they began to become more specialised for water hunting and living, and eventually grew into the animals we know today!

Something I've always wondered is whether ichthyosaurs were ectothermic or endothermic. Fish obviously are cold-blooded but scientists think dinosaurs were endothermic or misothermic, and the archosaurs of today (crocodilians) are ectothermic. I guess this question extends to the other marine reptiles like mosasaurs and plesiosaurs.

No expert on the matter, but it might’ve also had something to do w/ their means of reproduction. (Most) reptiles when they’re born are practically set and ready to go vs mammals who take longer to gestate the bigger they get and will need parental care and feed off milk. Of course, this is merely me guessing.
