Generalized stratigraphic distribution of selected latest
Permian and Early/Middle Triassic spore and pollen types in Europe.
For information on the botanical affinity of the spores and pollen, see
Table 1. The ecologic crisis and associated conifer extinction is
marked by a proliferation of fungal remains (9, 11, 86). It should be
noted that first appearance of the conodont Hindeodus
parvus is presently recommended to mark the onset of the
Triassic (87). One of the implications of this definition is that the
crisis occurred before the P–Tr boundary, rather than at the
boundary. Preceding the successional recovery of conifer-dominant
vegetation, postcrisis repopulation is characterized by a prolonged
bryophyte/lycopsid-dominant survival phase (terminology after refs.
3–6). For absolute age estimates, see text.
