Apart from the above taxa, Nehring (1898) described from one of the three localities Dolomys milleri Nehring, an index fossil of Beremend-aged faunas to this day.

Fig. 13. Characteristic index fossil of the older phases of the Middle Pleistocene, the vole Mimomys savini Hinton, (a) and (b) Occlusal surface of the first molar of a young and an adult specimen (c) and (d) same from lateral view occlusal surface of (e) M2 (f) M2 and (g) M] (upper first molar). Characteristic from lateral view is the weak development of roots. Locality rock shelter of Tarkd.

The crested Porcupine Hystrix), as an index fossil , substantiates the allocation of two more faunal assemblages of lesser importance to the Varboian stage. One of these is from the Biikk Mountains. A collection of a few bones was found in old collections of the Department of Palaeontology of the Hungarian Natural History Museum. According to the specimen labels, the bones were collected in 1936 by...

Mass extinctions have been recognized in the fossil record since the middle of the nineteenth century. Levels of mass extinction of species were selected as marker levels in the stratigraphic record because the death of index-fossil species provided a convenient marker to subdivide and correlate strata. The mass-extinction level called the Permian-Triassic boundary is so profound in terms of faunal and floral change that it was early on noted and chosen to represent the transition from Paleozoic to Mesozoic era. The mass-extinction level called the Cretaceous-Tertiary boundary is also quite distinctive in terms of faunal and floral change, and it too was noted early on and chosen to represent the transition from Mesozoic to Cenozoic era. Other less profound, but nevertheless distinctive levels of mass extinction of fossils have been selected to represent marker points in the stratigraphic record at which geological periods, epochs, ages, and other intervals of lesser temporal value are defined. 

This all sounds good in theory, but in actuality the only place that the geologic column is ever found is in textbooks. It is not a reality in the field. In other words, you can t take a drill, bore down into the earth, and from the core samples retrieved see the geologic column of fossils and rocks stacked up one upon another. Evolutionist scientists admit this, but the fact that students are taught the geologic column shows the bias that secular, humanist education takes. Students are given the impression that these rock layers can be found neatly placed one on top of the other, with these convenient index fossils present to indicate the age of the rock. This is patently false. 

Thin have become even more suspect since one of the creatures used as index fossils—graptoUtes, said to have lived 410 million years ago— have been found aUve today in the South Fhdfic And there is also the mysterious fossil of the trilobite, said to have lived 500-600 rruUion years ago, found inside a fossilized sandal print. How could a person wearing sandals. 

The ideal conditions for the formation of fossils occur in areas of rapid sedimentation, especially those parts of the seabed that lie below the zone of wave disturbance. See also CHEMICAL fossil INDEX FOSSIL MICROFOSSn.
