The Mammals that Lived Alongside the Dinosaurs

This video looks into the tiny mammals that lived in the shadow of the dinosaurs showing how diverse they were and explaining a little bit about how they evolved into their current groups.

I love your channel, however I do have one criticism; your source for the flying icthyoconodons is um... controversial to say the least. The hypothesis and “papers” justifying the existence of ancient flying non-bat mammals were not made by a scientist and not peer reviewed, the author merely another David Peters in regards to behavior and production of crackpot ideas based on little evidence. Would suggest adding a disclaimer in the video description to let viewers know that the evidence for non-bat aerial mammals isn’t all that substantial as well as unlikely.

I had never heard about mammals having night time adaptations as a group but it makes a lot of sense.

I just want to point out how much skill it took for the artist to draw the thumbnail. The perspective from below the water required so much detail and precision. Great job!

Thanks for the video.
One minor correction: most non primate mammals do see color; just not as well. Mammals lost 2 of the 4 primary colors their therapsid ancestors had. Old world primates gained the ability to see a third primary color. It's a bit more complicated with new world primates.

Oh man this is good stuff. I will throw you a dollar on patreon just so that I can brag about being your 4th patreon when this channel gets big.

My new, favourite "evolution" channel! Great vid on an often overlooked subject in paleontology. Thanks.

Normally people will just tell you "nah the dinosaurs took all the roles and niches, leaving mammals to all turn into rats and crap" but they were so much more diverse than i could ever imagine.

Funny how the documentaries that talked about dinosaurs in the era they live in never touch the mammels. This was and enjoyable learning experience

Its so sad that this video dodn't get as many views as your last two. You are an excellent source for all things prehistoric. I am so glad you are here on Youtube

I knew mammals walked alongside dinosaurs but I didnt realize for how long. Its almost insane to separate the two anymore. Such a neat video.

As we find more and more fossils, it is fascinating how "bushy" the Mesozoic mammal family tree was. As with more recent fauna, gone are the simple one specie lines (such as the 19th-century horse series or the 1960s Rudolph Zallinger's "The Road to Homo Sapiens" come to mind) and the ever-decreasing number of ghost lineages than we had say mid-20th century.

I was walking my dog at night and we saw a possum. Imagine seeing an animal that was around when the dinosaurs were around at the end of the Cretaceous Period. I wonder if my dog and I have a new found respect for our mammal brother, and their tenacity, and their strong family values to protect young during the dinosaur period. So much drama, dedication, and struggle. Thanks.

Found this channel about 2 weeks ago via reddit and literally watched every single video. Great content! Can anybody recommend any other channels that makes videos about evolution such as this one?

[AndreastheRed]

Found your channel through Reddit (I think) a week ago. Loving your content, keep it up!

Thanks for making a video on prehistoric mammals

The amount of work that you've put into these videos boggles my mind. Amazing. A minor complaint I would make would be the way you acknowledge the creators of the various artwork shown. It's a bit confusing. The text changes in size depending on how much of the screen the artwork covers so that sometimes the artists name looks like an acknowledgement but other times it looks like it's part of the narration. I'd suggest changing the font size so it appears a consistent size, give it a unique color to differentiate it from the editorial text and give it a prefix like 'Artwork by'. Thanks.

I literally just subscribed and you immediately post a new video... that's excellent timing.
Loving the videos so far, keep up the good work.

i did not expect that about opossums! what a curveball!

I believe the mammals, who were generally much smaller, likely survived for the same reason some of the avian dinosaurs did: they didn't require as much in the way of food. I think what really killed off the non-avian dinosaurs and other big creatures was the dying of many plants. Some plants survived, but not nearly enough for big herbivores, whose survival was also necessary for big carnivores to have enough to eat. Being smaller would have been a huge advantage at that point in time.

So my DNA has had been a nocturnal for 160million year and diurnal for 66million year?
No wonder I always feel sleepy at day time and energetic at night time.
