I find it fascinating that a group of reptiles grew nearly as diverse and prominent during the mesozoic as the dinosaurs did. We think of that time as the era of stem bird rule but this group of animals as well as the archosaurs in the air and sea shows that it wasn’t just the dinosaur show.

That’s very true. Pseudosuchians were important components of many Mesozoic ecosystems, being far more diverse than today.

When I told my nephew that crocodilians have a wide variety of ancestors he was baffled. Because it is always better to give correct info I showed him this video. He liked it very much and went on to see some other episode on your channel. Sadly these days children are not enough stimulated to discover things. To search for answers or to just find cool stuff like dinosaurs. All they want (and do) is play those XBOX games. There is so much to discover out there. When I was a child (long ago) I got fascinated by history and palaeontology. All my allowance was spend on books. Maybe I was a bit too geeky. Still I had friends who used to build these airplane maquettes. These girls knew all about the plane they built. They researched it before putting it together. … Well I hope I can keep on interesting my nephew in gathering knowledge. Having a wide knowledge is so important to understand the changing world.
@lilitheden7483 жыл бұрын
@Dan Won I see,what you mean. It’s not so that I forced him to like dinosaurs and stuff. I just wanted to broaden his knowledge. It was his choice to continue watching the channel. If he wouldn’t have liked it well then so be it. You can’t make someone like things. About playing games, he does play a lot. His mum complains about it. It’s maybe because of the isolation. When playing he can speak and interact with his friends and I guess that is the attraction of it. I know that playing games doesn’t make people stupid and can make them interested in programming or developing games and such. There have to be also other interests and those can vary from sports to painting or horseback riding… It changes the way you look at the world and in a way makes you the person you are.
