Heloridae
Heloridae is a family of wasps in the order Hymenoptera known primarily from fossils, and only one extant genus, '' Helorus'', with 12 species found worldwide. Members of ''Helorus'' are parasitic on green lacewings.

Helorus Anomalipes
Helorus, Heloros, Helorum, or Elorus (Greek: or , Ptol., Steph. B. or , Scyl.; it, Eloro), was an ancient Greek city of Sicily, situated near the east coast, about 40 km south of Syracuse and on the banks of the river of the same name. It is currently an archaeological site in the modern ''comune'' of Noto. History We have no account of its origin, but it was probably a colony of Syracuse, of which it appears to have continued always a dependency. The name is first found in Scylax; for, though Thucydides repeatedly mentions the road leading to Helorus from Syracuse, which was that followed by the Athenians in their disastrous retreat, he never speaks of the town itself. It was one of the cities which remained the under the government of Hieron II by the treaty concluded with him by the Romans, in 263 BC: and, having during the Second Punic War declared in favour of the Carthaginians, was recovered by Marcus Claudius Marcellus in 214 BC. Under the Romans it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinuiju Formation
The Sinuiju Formation is a geologic formation in North Korea. Formerly of uncertain age, it is now thought to be Early Cretaceous. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. Compression fossils of insects are also known from the formation. Several bird fossils are found in this formation, including a very large enantiornithine specimen with a long tibia and a long pygostyle. Amphibian fossils, including frogs and lissamphibians, have also been found here. Fossil content Fish * ''Lycoptera'' sp. * Acipenseriformes indet. Amphibians * Anuran (a frog, might be referred to '' Liaobatrachus grabaui''). Pterosaurs * Anurognathidae indet. Birds * Confuciusornithidae indet. (known colloquially as the ''Archaeopteryx'' of Korea) * Enantiornithes indet. * Ornithurae indet. Insects [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxfordian (stage)
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 163.5 ± 1.0 Ma and 157.3 ± 1.0 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Oxford, Bedford, Peterborough, and in the cliffs at Scarborough, Red Cliff and Gristhorpe Bay. Rocks of this age are found also in Uig and Skye. The base of the Oxfordian Stage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karabastau Formation
The Karabastau Formation ( kk, Qarabastaý svıtasy) is a geological formation and lagerstätte in the Karatau Mountains of southern Kazakhstan whose strata date to the Middle to Late Jurassic. It is an important locality for insect fossils that has been studied since the early 20th century, alongside the rarer remains of vertebrates, including pterosaurs, salamanders, lizards and crocodiles.Barrett, P.M., Butler, R.J., Edwards, N.P., & Milner, A.R.

Zitteliana B, 28. 264p/ref> Lithology and depositional environment The primary lithology consists of 1 mm thick varve laminations of claystone, with a dark part and a light dolomitic part, which probably correspond to a wet and dry season respectively, alongside rare, several cm thick sandstone interbeds.
