Scientists Discover Two Mating Flies Trapped in Amber 40 Million Years Ago

Fossil Amber or Fossil Resin. Amber is the popular name for fossilized resin of botanical origin. The proper scientific terminology is fossil resin, but we will use the terms amber and fossil resin interchangeably. The word amber also denotes a golden color that amber predominately reflects recall that when human eyes see color, it is actually the portion of the visible light spectrum that an object reflects that is detected. In fact, amber reflects many frequencies of light, including red, green and blue that together constitutes the entire visible spectrum. Archeological findings show that amber was one of the first materials prehistoric humans used for ornamentation, with instances dating back as far as 30, years. Use of fossil resin for jewelry and other decoration continues unabated, and amber is often considered as a gemstone. Amber is also valued for its botanical and animal inclusions that are trapped by the sticky resin as it flows as sap, which is also organic.

Fossil dating methods

About 99 million years ago, a tiny juvenile frog in present-day Myanmar was suddenly trapped in sap with a beetle, perhaps its intended next meal. An extinct species now named Electrorana limoae , it’s one of four fossils that provide the earliest direct evidence of frogs living in wet, tropical forests and are the oldest-known examples of frogs preserved in amber.

This is pretty special,” said David Blackburn, study co-author and the associate curator of herpetology at the Florida Museum of Natural History. These frogs were part of a tropical ecosystem that, in some ways, might not have been that different to what we find today — minus the dinosaurs. The findings and species description were published today in Nature’s Scientific Reports. Frogs have been around for at least million years, but glimpsing their early heyday is tough.

Nature is full of colors, from the radiant shine of a peacock’s feathers or the bright warning coloration of toxic frogs to the pearl-white camouflage of polar bears. Usually, fine structural detail necessary for the conservation of color is rarely preserved in the fossil record , making most reconstructions of the fossil dependent upon an artist’s imagination. Colors offer many clues about the behavior and ecology of animals. They function to keep organisms safe from predators, at the right temperature, or attractive to potential mates.

Understanding the coloration of long-extinct animals can help us shed light on ecosystems in the deep geological past. The study, published in Proceedings of the Royal Society B on July 1, offers a new perspective on the often overlooked, but by no means dull, lives of insects that co-existed alongside dinosaurs in Cretaceous rainforests. Researchers gathered a treasure trove of 35 amber pieces with exquisitely preserved insects from an amber mine in northern Myanmar. It is essentially resin produced by ancient coniferous trees that grew in a tropical rainforest environment.

Animals and plants trapped in the thick resin got preserved, some with life-like fidelity,” said Dr. The rare set of amber fossils includes cuckoo wasps with metallic bluish-green, yellowish-green, purplish-blue or green colors on the head, thorax, abdomen, and legs. In terms of color, they are almost the same as cuckoo wasps that live today, said Dr.

The researchers also discovered blue and purple beetle specimens and a metallic dark-green soldier fly.

Historic haul of Australian amber fossils includes ants, spiders and fornicating flies

All rights reserved. More than a third of the 7,odd living species of frogs and toads are found in rain forests around the world. But the fossil record for amphibians from these kinds of wet, tropical environments has been almost nonexistent, leaving paleontologists with few clues to their early evolution. Now, lumps of amber dating back to the Cretaceous period have revealed a set of four tiny tropical frogs that lived alongside the dinosaurs, making them the oldest frog fossils of their kind.

Dating Fossils – How Are Fossils Dated?

About 41 million years ago, two long-legged flies had just begun an amorous tryst when they were caught fast in sticky sap, which eventually hardened around their joined bodies to form an amber tomb. The last moments of these mating flies, now locked in amber, offer a fascinating window into life in the Eocene epoch around 55 million to 34 million years ago , which is part of the Paleogene period.

This remarkable “frozen behavior” is one of many amber specimens that scientists recently discovered in Australia; researchers examined thousands of amber pieces from a site in western Tasmania and from other locations in Australia and New Zealand, describing highlights in a new study.

Some vendors hawk jade or snacks, but most everyone is here for the amber: raw amber coated in gray volcanic ash; polished amber carved into smiling Buddhas; egg-size dollops of amber the color of honey, molasses, or garnet. Some browsers seek treasure for their own collections, whereas others act as virtual dealers, holding amber pieces in front of their smartphones and snapping images for distant buyers.

For scientists, this is more than a place to buy pendants or bracelets. One morning in March, paleontologist Xing Lida from the China University of Geosciences in Beijing stops at a table and examines a cockroach in a golf ball—size glob of amber, paused in time from the middle of the Cretaceous period.

The fossil of the long-legged flies with their proverbial pants around their ankles is now one of Australia’s oldest on record. Though some couples boldly declare themselves to be so good at fornication they ought to be immortalized for it, they’ve been beaten to the punch by two long-legged flies preserved in amber. A new study, published in the journal Nature on Thursday , suggests the flies are evidence of some of the oldest known Australian fossils to be preserved in amber.

They’re also potential candidates for the first frozen mating behavior to be listed in Australia’s fossil record. Led by a team from Monash University’s School of Earth, Atmosphere and Environment in Melbourne, the study unearthed more than just some randy flies. Researchers also discovered the oldest known fossil ants from southern Gondwana, the first Australian fossils of wingless hexapods — known as “slender springtails” — a cluster of spiders, two liverwort, two moss species and biting midges, all encased in amber.

The team — made up of scientists from Australia, Spain, Italy and the UK — studied amber pieces found in Tasmania’s Macquarie Harbour Formation and Victoria’s Anglesea Coal Measures, dating back over 50 million and 40 million years respectively. Sure we can all giggle about these long-legged flies getting caught with their long legs in a compromising position, but it’s actually a huge step forward in learning more about Australia’s prehistoric beasties and extrapolating what it might mean now.

Mosquito dating back to age of dinosaurs found preserved in amber & it might have carried malaria

An entomologist examining wasp specimens in fossilized amber from the Eocene 34—55 million years ago has identified them as a new species, Brachyelatus marthae , and the first fossil specimens from the chalcid wasp subfamily Chrysolampinae. Most of the mined amber in the world winds up as gemstones in earrings and necklaces, but sometimes it has a greater purpose: It makes its way to entomologists who find beautifully preserved prehistoric insects inside.

A case in point is the new report of never-before-seen wasps found in Baltic amber dating back at least 40 million years. The museum had already narrowed down about of the samples to a group of small wasps in the superfamily Chalcidoidea, but they needed a specialist to do more detailed identifications. Burks is one of only a handful of people in the world with that expertise, and fortunately he had time in his schedule to make the trip to Germany.

Even though the insects were just 2—3 millimeters mm long and encased in rock-hard sap, his knowledge of extinct and extant still-existing wasps allowed him to quickly sort the samples into their proper families and subfamilies.

Forty or so million years ago, on the southern end of the Gondwana supercontinent, two mating insects unexpectedly found themselves in a sticky situation – and not in a good way. Somehow, this pair of busy long-legged flies Dolichopodidae had gotten themselves trapped in the gooey sap of a tree, and there was simply no escape. That moment spelled both the beginning and the end of this casual love affair.

Frozen in intimacy, the resin turned to amber, and the moments of copulation turned into something more enduring. In , the precious scene fell into the hands of palaeontologists working in the Otway Basin of southern Australia. At first, lead researcher Jeffrey Stilwell from Monash University said he couldn’t believe his eyes. It’s not unusual for small ancient creatures to be found in fossilised resin, but for some reason it’s a rarity to find such specimens in the Southern Hemisphere, much less one where two creatures are frozen in the act of mating.
