On Sunday I took a trip to the Natural History Museum in London. I queued up before it opened at 10am and even before then there was a long queue. I have not visited this museum since I was a child and spent an entire day there (10am to 4.30pm - a long time). I was surprised as it is a lot bigger than I remembered and there was so much to see. This place has the most wonderful things and is an incredible place to learn. The museum showcases a Baryonyx, Sophie the Stegosaurus (the world's most complete Stegosaurus) and more! The moving Trex and Deinonychus are also really realistic in the way they move. If you like your dinosaur teeth, the Megalosaurus and Daspletosaurus teeth are out of this world! There is something for everyone in this museum and I would highly recommend that you visit here if you have not already! A lot of the dinosaur specimens are casts taken from other museums but they are still cool to look at. I had taken the photos on my SLR and due to the size of the photos I had to reduce the quality of them to be able to post on the forum which is unfortunate but it's the only way otherwise the photos would take a really long time to load. There are more non-dinosaur related photos that I will be posting at some point later on but may take me some time to pick out. Enjoy the photos from this section of the museum!

Upsurge in big earthquakes predicted for 2018 as Earth rotation slows
Oxytropidoceras posted a topic in Geology
Upsurge in big earthquakes predicted for 2018 as Earth rotation slows. Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth’s rotation. the Guardian. https://www.theguardian.com/world/2017/nov/18/2018-set-to-be-year-of-big-earthquakes Sloshing of Earth’s core may spike major earthquakes By Paul Voosen, Science, October 30, 2017 http://www.sciencemag.org/news/2017/10/sloshing-earth-s-core-may-spike-major-earthquakes Bilham, R., and Bendick, R., 2017.

Ive been through many earthquakes in California, some small some rather large and dangerous. None of those earthquakes made any noise. Last night, (I live outside of Helena Montana), both my wife and I were wakened up by ground shaking and then realized it was a very noisy earthquake! My wife was very frightened. I figured it was over, but was now wide awake. Then about 10 minutes later we both heard a very strange noise but no ground shaking. Figured it was a small aftershock. Then another 20 minutes or so and we heard another really loud noise comin our way the house begins to shake! After 2 more of those everything quited down. The most bizzar night I have ever experienced!!! Im gunna havta run into town and get the newspaper and see what and where. We dont get any local news. RB
