Cretaceous succession of insect assemblages in China
By LIN QI-BIN*)
INTRODUCTION
The Cretaceous non-marine sediments are well developed Sinosirex gigantea and Sinoeschnidea heishankowensis, des both in North and South China and yield the richest insect cribed by H ong (1975) from Hebei and several insects recor fossils in East Asia. The Johol fauna carrying insect, Ostraco- ded later by H ong and W ang from other Lower Cretaceous da, Conchostraca, Bivalvia, Gastropoda and fish fossils is beds of Inner Mongolia and Hebei Province; more recently, well known as notable animal remains in the world, because it the present writer made a discovery of still more fossil insects appears to have been widely spread over North and East of the same age from some important localities and described China and extensively used for the examination of specific more than fifty-two species (L in , 1976, 1978, 1980). ages and the correlation of rocks in various parts of China in Based on these studies and concerned with the informations paleontological researches. Since 1923, in addition to the pu about other animal or plant fossils, the insect of the Creta blication of “ Cretaceous Fossils from Shantung” a number of ceous in China can be grouped into three assemblages, the insect fossil materials have been collected and studied, such as succession of which is briefly given below: 1. Coptoclava as a Cretaceous beetle, Umenocoleus sinuatus from Gansu pro semblage, 2. Solusiparorpa assemblage and 3. Siculocorixa vince described by C hen et T’an (1973). A few insect fossils, assemblage.
1. COPTOCLAVA ASSEMBLAGE
This assemblage is considered to be Lower Cretaceous, of Coptoclava longipoda larvae in the Dalazi Formation composed mainly of Coptoclava longipoda, Mesolygaous which are known as a kind of younger beettle. So far as laiyangensis, Mesoblattina sinica, Chironomapsis gracilis, Si knowns, the formation is one of the definitely established nosirex gigantea, Sinaescbnidia heishankowensis, Clypo- Cretaceous beds in China. In some outcrops of this forma stemma xyphiale, Ratiticorixa stenorhinchis, Vulcanicorixa tion, abundant larvae of Coptoclava longipoda have been dorylis and Penaphis circa including the following forma found with no other insect fossils being associated with them. tions: Dalazi Formation of Jilin Province, Shahai Formation But in other outcrops of the formations of this assemblage, of Liaoning Province, Laiyang Formation of Shantung Pro they were found in association with Mesoblattina sinica, Chi vince, Lushangfen Formation of Beijing, the upper member ronomapsis gracilis, Mesolygaous laiyangensis etc. As one of of Shouchang Formation in Zhejiang Province, Huoshangpu the important elements in the assemblage, appears to have Formation of Shanxi Province and Xiagou Formation of been widely spread over North and East China. However, as Gansu Province. The shale or mudstone in these formations these younger larval beettles were not well-preserved, many are generally thickbedded and rich in insect fossils. younger geologists, sometimes, incorrectly identified them as Among the significant species are Coptoclava longipoda, Ephemeropsis trisetalis when they are on field work. Mesolygaous laiyangensis and Mesoblattina sinica. A number

2 . SOLUSIPARORPA ASSEMBLAGE
This assemblage is one more insect fauna of Lower Creta and Zhongou Formation of Gansu Province belong to this as ceous, probably representing late Lower Cretaceous. Forma semblage, in which are contained important elements: Solusi- tions such as Guantou and Zhaochuan in Zhejiang Province, parorpa gibbidorsa, Cbiromomaptera melanura and Tapha- the upper memberof Yantang Formation in Anhwei Province cns turgis.
3. SICULOCORIXA ASSEMBLAGE
In the Upper Cretaceous, this assemblage is represented by also found Siculiconxa estria. Although this assemblage is the formation of Juezhou Group of Zhejiang Province. The very little known in China, its non-marine sediments of Cre insect bed lies at the middle of the group, carrying dominant taceous were well developed. Hence, a very rich content of in element Sicuhcorixa estria and others such as Clypostemma sect remains may be expected in the beds of Upper Creta limna and Prionocephale deplanae. In the Upper Cretaceous ceous. insect bed in Xingning region of Guangdong Province was
