"Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument[1][2][3] saline soda lake located at Lonar in Buldhana district, Maharashtra, India, which was created by a meteor impact during the Pleistocene Epoch[4] and it is the only known hyper velocity impact crater in basaltic rock anywhere on Earth.[5]"
Close to where I grew up there is the Nördlinger Ries
https://en.m.wikipedia.org/wiki/N%C3%B6rdlinger_Ries. It looks pretty obvious on maps and when we made school trip there I was really disappointed that you have to look really hard to recognize it.
I thought it would look like the meteor crater in Arizona.
And linked from there, the Toms Canyon impact crater:[0]
> The crater dates to the late Eocene geological time period (about 35 million years ago), and may have been formed by the same event as the larger Chesapeake Bay impact crater (and possibly the Popigai crater in Siberia), 320 kilometres (200 mi) to the southwest at the mouth of Chesapeake Bay, and also dating to the late Eocene.
Wow,
So Dinosaurs began 230 million years ago and ended just 66 million. So they dominated for a significantly longer period than mammals have so far been dominant. And all the eras of the evolution has involved proportionately shorter time periods. Puts the various exponential processes of human development in some kind of perspective.
I read somewhere we live closer in time to the t-rex than some other other dinosaurs (like the stegosaurus). Really got me thinking about how vastly longer the dinos have walked the earth.
I later learned that my home town is on the edge of Europe's largest impact crater. https://en.m.wikipedia.org/wiki/Siljan_Ring
Most people seem to just... not care. :)

Nowadays they're eyeing closely something SW of it, underwater, in the St. Laurence.
