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.
Its remains were discovered in 1919. Reconstructed from the scattered bits and pieces of its exoskeleton, R. praecursor was described in 1926, and at first believed to be a larval insect . [ 2 ] This study also described euthycarcinoid Heterocrania , and supposed larval insect mouthparts, later redescribed as Rhyniognatha hirsti in 1928 [ 1 ...
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 ...
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).
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.
Because fossil insect eggs are so scarce, there weren’t many specimens available for comparison. So Lee consulted a global insect egg database, containing more than 6,700 living species, to ...
Paratype worker of S. freyi. Before the discovery of the first Sphecomyrma fossils, there were no fossil records of any ants from Cretaceous amber and the oldest social insects at the time extended back to the Eocene epoch; the earliest known ant at the time was described from a forewing found in the Claiborne Formation [A] in Tennessee.
