This is a sentence of the lesson «How old is it? Rock layers, rock clocks, amber and the long story of life» of the biology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Trilobites), what happens, when and where, as Mova's frames read it from the tree.
