Hindeodus

• Asia (China)

Hindeodus parvus is a species of conodonts ( Conodonta ), the first time leading in the fossil rocks of Meishan was found in Changxing county in Zhejiang province, China.

Like other conodonts also serves as an index fossil Hindeodus parvus. His first appearance in the stratigraphic sequence of sedimentary rocks documented the beginning of the geological section of the Indusiums. The indusium is the oldest chronostratigraphic stage of the Triassic and thus are the oldest copies of this conodonts in the fossil record for the turn of the youngest Permian ( Lopingium ) to the oldest Triassic and also the beginning of the Mesozoic era ( Mesozoic ).

Features

The conodont apparatus of Hindeodus parvus, as with all species of the genus of six different types of elements. The platform elements ( Pa) are small follow with a tall, slender and upright, slightly rearward or curved gear, the 4-9 much smaller teeth. There can be distinguished two morphotypes, between which, however numerous transitional forms occur. The smaller teeth in morphotype 1 are slimmer and all about the same. The rear of the item drops here significantly and bears no teeth. In morphotype 2, the teeth are slightly longer with a slightly sloping from the peak top. The rear third of the platform element is covered with numerous small, inclined teeth. Astform the elements (R) have a relatively short, high beam for Hindeodus. When Sb element, the tip and occasionally the first word of the rear bar is included in contrast to all other Hindeodus species in the strong inward bending of the front beam.

Dissemination

Hindeodus parvus was disseminated throughout the Tethys.
