In the first edition of Genera Palmarum (1987), Natalie Uhl and John Dransfield placed the genus Zombia in the subfamily Coryphoideae, the tribe Corypheae and the subtribe Thrinacinae using Harold E. Moore's 1973 classification of the palm family.
In the first edition of Genera Palmarum [16], this relationship was explicitly noted, but was expunged from the second edition [14], based on Gunn's [5] weak resolution of Cocos as sister to Parajubaea with ML.
In 1842, Owen made Megalosaurus one of the first three genera placed in the Dinosauria.
Because Iguanodon is one of the first dinosaur genera to have been named, numerous species have been assigned to it.
One of the first named genera was Ceratops itself, which lent its name to the group, although it is considered a nomen dubium today as its fossil remains have no distinguishing characteristics that are not also found in other ceratopsians.
For example, the first appearance of extinct genera Trogonictis and Sminthosinis and extant genera Lutra and Mustela help mark the latest Hemphilian NALMA (Late Miocene-Early Pliocene, 5.9-4.7 million years ago (MYA)) [ 19].
Caruso [ 30] presented the first cladogram of lophiid genera based on 19 morphological characters, of which 12 showed derived states shared by two or three genera.
Our study is the first record of several genera from the GOM and western Atlantic, namely, Thoracostomopsis, Micoletzkyia, Phanoderma, Phanodermella and Synonchus as they have not been considered in previous meiobenthic studies in these regions [30].
During the second stage, the two genera of bacteria formed a relatively stable community and degraded lignin derivatives, which resulted in the reduction of the chromophores of lignin derivates correspondingly.
This is the first published hypothesis of relationship among genera of the Erythrinidae and should be tested in further studies in this family.
