Pteridophte resources are rich in Guizhou, China. More than 700 species, belonging to 150 genera and 53 families, have been known so far Many of them are of edible, medicinal and ornamental value, and the rare and endemic species attract pteridologists being engaged in their research. Pteridophyte protection is much necessary and natural reserves provide an efficient method for most of them in Guizhou. For better study and use, the establishment of special fern section or garden is of significance. A project of setting up a fern section in Guizhou Botanioal Garden is being carried out. It is hopeful that it will be one of the ideal bases as a gone pool of subtropical ferns in China. 相似文献

Ichthyosaur from Guizhou, China 总被引:9,自引:0,他引:9
Chun Li 《科学通报(英文版)》1999,44(14):1329-1329
A new ichthyosaur is named and described on the basis of two well-preserved skeletons from the Late Triassic Wayao Member
of Falang Formation, Guizhou Province, southwestern China. The specimens represent a longipinnate ichthyosaur with a set of
characters transitional from the Triassic forms to the Jurassic forms. It is similar to shastasaurids of the Triassic in the
relative size and shape of the limbs but resemblesOphthalmosaurus andBaptanodon of the Jurassic in the shape of the skull. The new taxon differs from all other ichthyosaurs found in China in its unusual
large orbit, distinct rostrum, and the hind limbs, that are slightly stronger than the fore ones. 相似文献

Sauropterygian from Triassic of Guizhou, China 总被引:6,自引:0,他引:6
Jun Liu 《科学通报(英文版)》1999,44(14):1312-1312
A new sauropterygian,Anshunsaurus huangguoshuensis, is described on the basis of a well-preserved skull from the Late Triassic Wayao Member of Falang Formation, Guizhou Province,
southwestern China. It is ascribed to Eusauroptetrygia because it possesses the following characters: the rostrum is mainly
composed by the premaxillae; the nasals are small, paired and separated from one another by the premaxillae; the external
nares are close to the orbits; and the frontals are fused.Anshunsaurus differs from other Triassic sauropterygians in its large size, long rostrum and the supratemporal fenestrae slightly smaller
than orbits. It is further considered to be closely related toPistosaurus on the basis of the nasals contact with the prefrontals; large pineal foramen, lain in the anterior part of the parietal
table; the squamosals not in contact posterior to the supratemporal fenestra. The discovery ofAnshunsaurus with the ichthyosaurs in the same locality indicates a new assemblage of Triassic marine tetrapods in China. 相似文献

A new cyamodontoid placodont is named (Psephochelys polyosteoderma gen. et. sp. nov.) and described based on a three-dimensionally preserved specimen. The material comes from the Wayao Member of the Falang Formation (Carnian, Late Triassic) in Guizhou Province, southwestern China. The skull of Psephochelys shows a unique combination of characteristics observed in Psephoderma and Placochelys, and the carapace is diagnostic of a new taxon as well. The ventral dermal armor of Psephochelys differs from all other known cyamodontoids in that it comprises irregular marginal osteoderms in loose contact with each other, and gastralia between them. The cranial suture pattern is in part difficult to analyze due to apparent co-ossification of elements, or poor delimitation of sutures.This affects primarily the demarcation of the nasal from the prefrontal, and the relation between the anterior part of the parietal, posterior ends of the frontals, and postfrontals.However, the postfrontal appears to enter the anteromedial margin of the upper temporal fenestra, a characteristic otherwise known from Placodus, but not from other cyamodontoids. However, given the difficulties of interpretation of this skull, additional material is required to unequivocally assess some details of the pattern of cranial sutures. 相似文献
