The China Dinosaurus exhibition in the Maastricht library draws to an end. I went there today to make some more sketches. The first one is a 8 meter high Yangchuanosaurus. You would not like to meet him 150.000.000 years ago. The bottom one is a Mamenchisaurus. In reality his neck is 3 times as long, but it did not fit on the page. To see its head, see my post of 2 weeks ago.
