Nigel goes to modern Arran (in a large RIB with an A-frame and a steering wheel), and sees a fossil Arthropleura track in rock. He talks about what Arran was 300000000 years ago. He goes back to the park to serious trouble among the Tyrannosaurus: Matilda has broken into Terence's enclosure: Terence has refused to allow his sister to intrude on his territory and a fight has broken out, in which Matilda is gaining the upper hand. Terence has been badly bitten about the face. On site, Nigel wades through a swamp. Something big moves about underwater and makes bubbles. Nigel hears something big moving about in undergrowth on land, and chases it, and finds an Arthropleura. It rears and confronts him. It is 10 feet long and has big dangerous-looking mandibles. Some modern millipedes (see Harpaphe haydeniana) can squirt cyanide, which smells of almonds, and Nigel fears that Arthropleura may also. Nigel says that that may be the same track that he saw fossilized on modern Arran. He sees two male Meganeura have a dogfight. Afterwards, one flies away and the other looks for food. Nigel has a butterfly net, but a butterfly net big enough to catch a Meganeura is cumbersome. As Nigel makes a move to catch a Meganeura, something in the water bites his right ankle. He says "Animal bites for us wildlife folks are just a badge of courage." They look for a dry area to camp. Evening is coming. The crew camp for the night.
