The two flies were in contact with resin, stuck in a sensitive posture for 41 million years

A study related to amber fossils was published yesterday on the Scientific Reports page, which provides quite a number of unique images of spiders, ants, and a pair of prehistoric flies. love again.

Amber fossils are quite common in the Northern Hemisphere, especially in Myanmar, where various types of fossils have been discovered over the years. However, this new collection is one of the oldest amber fossils collected from the southern hemisphere, including excavations in Australia and New Zealand. The research leader was Jeffrey Stilwell from the Earth, Atmosphere, and Monash Environment School.

The new collection (pictured below) has a fairly long time span, extending from The Late Triassic about 230 million years ago, to The Eocene End of Middle Ages some 40 million years ago. Stilwell and his colleagues unearthed thousands of pieces of amber, many of which contained all sorts of animals, plants, and microorganisms.

Amber fossils are valuable because they show 3D models of preserved specimens indefinitely. In rare cases, these fossils can also capture a specific behavior, such as a tick crawling through a dinosaur’s fur, or a spider attacking a wasp. In this case, the researchers found a pair of lovingly long-legged flies (Dolichopodidae), which lived south of Gondwana during the End-Middle Eocene, which is now Anglesea, Australia.

This is probably the first example of ‘frozen behavior’ in fossils found so far in Australia“- Stilwell said.

But according to paleontologist Victoria McCoy from the University of Wisconsin, Milwaukee, the flies may not actually be in that position when they die. “It is possible that one fly becomes trapped in amber, and the other finds interest and attempts to make love“- McCoy said.

It sounds a bit ridiculous, but anyway, the two flies have already gone smoothly!

The story of two unfortunate flies is accidentally trapped in a sensitive position for future generations to admire is still quite lucky. In 2016, a 99 million year old amber specimen was found to contain a long-legged spider (pictured below) with an erect penis – perhaps the oldest and oldest erection in history. science!

And another awkward moment is a 100 million-year-old fossil specimen (pictured below) in China, including a male damselfly trying to make love to a female, and this unlucky man is also caught blue balls (blue balls, increased blood pressure in the testes make it impossible to ejaculate) anymore! At least those two long-legged flies had a chance to really “howl” together.

These amber fossils give scientists an unprecedented view of ecosystems that existed long ago south of Pangea, south of Gondwana, and Zealandia. Starting from 200 million – 175 million years ago, the lands that today are South America, Africa, Madagascar, India, Antarctica, and Australia began separating from the Pangea supercontinent and forming supercontinent. Small Gondwana.

In addition to the fly, the study described a newly discovered fossil ant, called Monomorium, and a small, wingless, rear-legged species, both from southern Gondwana. Other species found in the resin fossils this time were a bunch of baby spiders, some small insects, a plant called liverworts, and some moss. The scientists also discovered a fossil record dating back about 230 million years – the oldest ever seen south of Pangea.

Scientists will continue to list many types of animals found in amber, because many of them may be new species, and even new groups of animals.
