Abstract ▼ AI-Helper

Lower Ordovician (Upper Tremadoc) graptolites were found for the first time at the two sections of the Mungok Formation in Danyang area: the Seokgyori and Daejeonri sections. The graptolites from these sections comprise two species of two genera: Adelograptus brevibrachiatus and Psigraptus jacksoni. The graptolite faunas of the sections in the area show simple composition relative to Yeongwol area; they appear to be correlated to: (1) the Adelograptus cf tenellus Zone of Yeongwol area, (2) the Adelograptus cf. tenellus Zone of Yukon, Canada, (3) the Psigraptus Zone of Tasmania, Australia, and (4) the Psigraptus jacksoni Zone of Jilin, China. The age of graptolite beds of the Mungok Formation at Danyang appears to be early Upper Tremadoc of the Lower Ordovician.

Description: The rhabdosome is composed of reclined stipes deriving from two short and generally horizontal primary stipes and bifurcating further more or less regularly, for several times. The size of the rhabdosome in DJ-P003 specimen is up to 13.
Remarks: The Danyang materials morphologically similar to A. brevibrachiatus from Yeongwol area in having short funicle and subsequent stipes. Most of the characters such as branching o* rd as shown in Table 3, of the Danyang materials are similar to those of the Yeongwol materials.

Graptolites described herein were collected from two localities in the Mungok Formation of Danyang area: the Daejeonri and Seokgyori sections (Fig. 1). The Daejeonri section is exposed along the route 519 at the vicinity of Daejeonri village, which is ca.
Measured material is DJ-A002 (Fig. 3A, B) from the Daejeonri section of the Mungok Formation, Danyang.
Measured materials are DJ-P002, 003, 005, 006, 008, 010, SE-P003 and 005 from the Daejeonri and Seokgyori sections of the Mungok Formation at Danyang area.

Description: Rhabdosome small usually less than 20 mm in diameter, horizontal to declined, multirenous by biradiating up to 5th order, composed of 24 terminal stipes at least. Funicle length is ca.
The species assigned to a new genus Muemhigraptus by Zhao and Zhang, 1985, including M. sinicus, M. rigidus, M. paucibrachiatus and M. symmetricus, are regarded herein as identical to Psigraptus jacksoni, and consequently are regarded as junior synonyms of P. jacksoni. However, the validity of the genus Muemhigraptus remains open to questions, as more work concerning the proximal development should be done before the synonyms can be confirmed.

However, there are not any studies on the graptolites. Hence, this study aims to report graptolites from Danyang area which represents the westernmost occurrence of the graptolites in the Choseon Supergroup.
