Ammonoids Lytophiceras and Ophiceras are discovered in bed 13-1A to bed 16, and regarded as the zonal fossils of the early Triasic ammonoid Ophiceras-Lytophiceras zone, indicating the Early Triassic in age.
Several taxa of fossil mammals were collected from Songxiyao village, Qinggang county, Heilongjiang in 1988. They are Mammuthus primigenius, Equus hemionus, Equus sp., Coelodonta antiquitatis,Megqloceros ordosianus,Gazella sp., Bison exiguus, Bos primigenius?
Lichuan, located at the foot of the Wuling Mountain in southwest Hubei Province of central China, is well known in the world for the discovery of the living fossil Metasequoia glyptostroboides Hu >amp;amp; Cheng in the 1940s.
Fossil history and modern distribution of the genus Abies (Pinaceae)
The genus Abies has a fossil history and modern distribution pattern similar to that of Cathaya and Pseudolarix.
The only known Early Cretaceous bird embryo fossil has shown that precocial birds had occurred prior to altricial birds in avian history, and the size of the embryo and other analysis indicate it probably had a short incubation period.
Based on integrative data of systematics, fossil history, and morphological and molecular evidence of these genera, their origin, evolution and relationships were discussed.
In this paper we report several 3D-preserved rare star-like fossils with finely preserved soft tissues which were recovered from the Kuanchuanpu Member of the Dengying Formation in South Shaanxi, China in 2003.
Phosphatized Punctatus with mouthparts and its embryo fossils from the Lower Cambrian of Ningqiang, south Shaanxi, China
In order to improve research into Punctatus, more than ten thousand globular fossils were recovered by means of "Chemistry Retting".
On the basis of the study of these globular fossils, a series of Punctatus fossils with cone parts and finely preserved soft-tissue mouthparts and fossilized metazoan embryo were recovered.
Through research on characteristics such as shape, modality and structure of these fossils symbiotic with Punctatus emeiensis, the author found many possible embryo fossils including the evidence of gastrula-stage animal fossils.
A bed containing fossil remains of brackish-water and marine mollusks was recognized in these sediments; the bed accumulated, based on results of radiocarbon datings, 500-1000 years ago.
Catfish pectoral and dorsal spines are robust, they preserve well and they form most of the fossil remains for the genus Synodontis.
Radiocarbon dating, conducted on ten samples of aquatic and terrestrial fossil remains, and the occurrence of the Laacher See Tephra (LST) reveal that the sediment sequence comprises the Late Glacial and Holocene lake history since ca.
The Middle Eocene lake sediments of the Eckfeld maar are situated on the southwestern margin of the Tertiary High-Eifel volcanic field (Germany) and are well known for excellently preserved fossil remains.
Occasionally, also rare body fossil remains (exuvia) ofPhlyctisoma (Erymidae) are preserved, although it is very difficult to attribute to this decapod crustacean a real tracemaker activity.
