Iguanodon sinkhole in Bernissart

Around the skeletons of the iguanodons in the cran that cuts through the carboniferous, sediments have been found that come from lakes and swamps: Wealden clay. So it is not erosional material from rivers, which literally and figuratively undermines Edouard Dupont's original theory. That hypothesis assumes that this would be a valley or gorge where the iguanodons would have ended up. According to paleontologist-geologist Pierre Bultynck, the corpses would have drifted to the lowest point in the region. They piled up in the clay sediments and ultimately collapsed into a natural pit, the sinkhole.
