However, Gurovich and Beck argued that the p4 of Argentodites did not differ materially from that in the jaw they allocated to Ferugliotherium, and that Argentodites was based on a specimen of either Ferugliotherium or a closely related animal.
This debate involved botanists on both sides of the Atlantic and the final outcome was a decision by the 14th International Botanical Congress in 1987 that Amaryllis should be a nomen conservandum (conserved name, i.e. correct regardless of priority) and ultimately based on a specimen of the South African Amaryllis belladonna from the Clifford Herbarium.
The second species, P. blackfeetensis, is based on a specimen in the Museum of the Rockies (MOR 454), which was described by another notable paleontologist, Jack Horner.
Researchers have previously thought that Ectobius first evolved in Europe and Africa, scuttling around the region since at least 44 million years ago, based on a specimen preserved in Baltic amber of this age.
Based on a single specimen of each, Remigio and Hebert [12] provided initial evidence for the genetic separation of L. h.
In 2005, a new species of chewing louse, Psittacobrosus bechsteini, was described based on a dead specimen discovered on a museum skin of the Cuban macaw.
It is worthwhile to mention that because the current research is based on a number of specimens, a numerical analysis and more empirical studies would be useful to have a better validation of the proposed ANN models.
Recently, Sohmer and Davis ([2007]) stated, based on a study of specimens, that P. cephalophora from the Philippines and P. kotoensis from Taiwan are not conspecific, but they did not describe differences between the two species.
In 2006, however, based on a study of specimens collected in China, other scientists considered them to be independent species.
If a new species is described based on a number of fossil specimens, it is common practice to make sure that these specimens are deposited in a collection where they can be studied by other scientists.
As indicated in Table 2, there are four specimens that lack a PathVysion FISH result and two of these specimens are overlapping with HER2 CISH resulting in agreement calculations based on a total of 350 specimens for this comparison.
