Another way of looking at this is the fact that the first appearance of any higher taxon will be the same as the first appearance of the oldest lower taxon within the group.

Overall, Brownfield Woods had substantially higher taxon richness than Trelease Woods based on several estimators.
Does higher taxon diversity reflect richness of conservation interest species?
1998; Kron and Judd 1997; Prendini 2001; Wiens 1998; Yeates 1995) believe using actual species/genera as terminals in an analysis, even if only a few species are included from each higher taxon, is a superior method to using supraspecific or composite terminals in many respects, a compromise decision was taken here to allow for multistate scoring for each supraspecific terminal if the taxa used to score for that terminal differed in their condition in respect to that character state.
Henderson made this statement about the taxon Bulimus Meek and Hayden in 1935 and no one, except maybe Taylor [2] has made a compelling argument for inclusion in a higher taxon. "Bulimus" limneaformis is one of the more common species of the latter part of the Cretaceous and Paleocene of the northern Great Plains and some intermontane basins.

Mytilids had significantly higher taxon richness than dreissenids (Table 2).
He considered richness at the genetic, species and higher taxon levels, concluding that "complementary areas can also be more efficient than hotspots of either richness or rarity."
Although regression through species (or higher taxon) points may not properly (randomly) partition the existing variance (Pagel 1993), the partition pattern can vary randomly at different taxonomic levels.
