Hi Cu-Bird
You may recognize all the dinosaurs today in my gallery! That's right, it's all of us! So the last part of my tour ends right here on BC, where you can see some of the over 9000 species of dinosaurs that evolved from those who survived the Cretaceous extinction event and are alive today. All of us modern dinos have feathers and most of us can fly. We are all over the earth, in every habitat, so we have been one of the most successful species of animals anywhere! We are all descended from the meat eating dromeosaur maniraptor line.
If you are interested in the current thinking about the extinction event at the end of the Cretaceous, think beyond the asteroid hitting near the Yucatan. Scientists now think that was a part of it, but that there were other factors as well, including volcanoes in Siberia and the Deccan plain in India all erupting around the same time. Remember that extinctions do not happen overnight, this event may have taken years. Some scientists think diseases among the dinos may have been a factor, too. They had, in fact, been dying off for thousands of years prior to the extinction event.
If you are interested in reading about dinos, mom would recommend any book by Tom Holtz, Paul Sereno, Scott Sampson, Jack Horner, or Robert Bakker. All of these guys are interesting writers. Holtz has written a book for 12 year olds that mom loves! It has wonderful illustrations in it and lots of information as well. You may know Scott Sampson if you have little ones who watch Dino Train on PBS. He writes books for adults, too. All the info this month came from mom's head, but she's been reading about dinos for about 45 years off and on, and did the training in the new hall recently.
Thank you for your support all month long, if I become king, it is because of you! Hugs and a vote, as well as a gigantic HAPPY NEW YEAR! to all of you from me, Gizmo |
