My World Tuesday

This is the Natural History Museum in Balboa Park, San Diego. Back in September they had a wonderful dinosaur exhibit.

We found this hanging above the entrance. It is an Extinct Gray Whale, as yet an unnamed species. If you are interested in finding out more about those in the photos that I can identify, just click on their names.

And here are its eggs.

On the other side of the dinosaur, you can see the skeleton. It's always very interesting to me to see how we 'work'.

I forgot to identify this cat unless it was a toothless saber-tooth tiger but I don't think so.
Added note: Kay over at An Unfittie's Guide to Adventurous Travel, helped me out in my identification of this cat. Her brother identified it as an American Lion, and according to the page on the website found here also sent to me by Kay, thanks Kay, it is indeed an American Lion, extinct 11,000 years ago and is a third again larger than the African Lion. Thanks so much Kay and thank you Brother of Kay!

There were very beautiful murals on the walls.

I think we all recognize these.

This is an extinct Sea Cow. You can see the Manatee and Dugong here.
Not sure what these animals were but they look rather like the lemur.

Always interesting in what I can glean from various websites, and I found the following information from this one (the first link right at the top of my post).

"You probably heard how dinosaurs went extinct: they were all killed one terrible day when a huge object from outer space - a comet or asteroid the size of at least 100,000 Superdomes - slammed into Earth around 65 million years ago. But this description is not quite correct.

Yes, a meteorite did pack an enormous punch, but current research indicates that the extinction of dinosaurs is a much more complicated story. First of all, dinosaurs are not extinct. Birds are living dinosaurs - survivors of the turmoil that wiped out their relatives like the T. rex. So what caused the chaos 65 million years ago? There's no doubt a comet or asteroid hit Earth around that time, and no doubt the impact had deadly consequences for life on Earth. But other factors, including massive volcanic eruptions and changing sea levels may have also played a roll in wiping out at least half of all species alive at the time.

Look closely at extinct animals.

A wide range of plants and animals, both on land and in the sea, went extinct 65 million years ago. The ferocious Tyrannosaurus rex was one of the last species of nonavian dinosaurs. The ancient mollusks known as ammonites disappeared quite suddenly 65 million years ago. The closest living relatives of ammonites include squid and the chambered nautilus."

Reading the above at the museum's website reminded me of a conversation I had with Gregg several days ago. He is reading a very interesting book called "What Technology Wants" by Kevin Kelly, and the author wrote that:

There are 30 million species on Planet Earth right now.

200,000,000 years ago there were 15 million species.

There are more species today than ever before in the history of the earth.

I also learned that American Indians had been in America 10,000 years before Columbus arrived.

And lastly there are six billion people on the planet and a hundred billion web pages.
