Later, Stehlin and Schaub [19] argued that the dentition showed derived features with respect to Phiomys andrewsi and suggested that the material represented a new genus ("Genus novem aus dem Fayum", p. 266).
Although herbarium material for the genus is admittedly poor (Parnell et al. 2014), the type of C. sinensis, Handel-Mazzetti 9595, Yunnan, 2850 m, 31 July 1916 (WU), clearly shows the short thick pedicels, short-lobed calyces and peltate stigmas that accord with the images of material from China as well as the Thai and Vietnam material mentioned.
However, from the point of view of quantity of information or exhaustiveness, the most perfect definition (perfectissima definitio), i.e., the definition enumerating all four causes of the definiendum and not just its proximate genus (material cause) and specific difference (formal cause), is superior to any other form of knowledge (fol. 6rb).
In 1943, Barnum Brown and Erich Maren Schlaikjer, with newer, more complete material, established the genus Pachycephalosaurus.
We used the plant material from the genus Solanum section Petota as described in Jacobs et al. [ 9], which consists of 4929 genotypes representing 916 accessions.
Sidney Ash and Lea Grauvogel-Stamm, for type material of the new genus Equicalastrobus from the Triassic of Utah and New Mexico.
Pistosaurus longaevus material was assigned to genus and species by morphological and histological comparison with Pistosaurus material in the collections of SMNS, and by comparison to the description of Pistosaurus by Sues [ 8].
The bar plot showed that four oaks of the Ilex group and one oak (Q. robur) of the Quercus group seemed to share some ancient genetic material with the Castanea genus.
With more complete fossil materials available, a new genus, Schmeissneria (Ginkgoales), was established for the female Stachyopitys and officially separated from the male Stachyopitys.
