The oldest insect fossil has been proposed to be Rhyniognatha hirsti, estimated to be 400 million years old, but the insect identity of the fossil has been contested. [3] Global climate conditions changed several times during the history of Earth, and along with it the diversity of insects.
It has been considered in some analyses as the oldest insect known, as well as possibly being a flying insect. [1] Rhyniognatha is known from a partial head with preserved mouthparts from the Early Devonian aged Rhynie chert around 400 million years ago, when Earth’s first terrestrial ecosystems were being formed.
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
Researchers said they have discovered the oldest-known fossils of mosquitoes - two males entombed in pieces of amber dating to 130 million years ago during the Cretaceous Period and found near the ...
Rhyniella is a genus of fossil springtails from the Rhynie chert, which formed during the Pragian stage of the Early Devonian. One species has been described, Rhyniella praecursor . For some time it was believed to be the only hexapod from the Early Devonian ( c. 410 million years ago ) [ 1 ]
The oldest fossil record of hexapod is obscure, as most of the candidates are poorly preserved and their hexapod affinities had been disputed. An iconic example is the Devonian Rhyniognatha hirsti , dated at 396 to 407 million years ago , its mandibles are thought to be a type found only in winged insects , which suggests that the earliest ...
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there.
