One of the highlighted Konservat-Lagerstätten in my Rise of Animals post is Chengjiang (a.k.a. the Maotianshan Shales). While Burgess has the historical significance, in terms of importance and potential, Chengjiang is arguably more important (see Shu, 2008). Read the rest of this entry »

One theme that will be very prominent throughout is that of Konservat Lagerstätten, or sites of exceptional fossil preservation. Whereas 99% of the fossil record consists of bones, shells, teeth and other hard parts, these localities preserve soft parts, such as muscle and tissue. We will see just how important this is in general for palaeontology, but also in the study of this particular topic of the origin of animals. Read the rest of this entry »
