Dinosaur age fungi discovery

Here are 10 extraordinary fossils that have been found preserved in amber. Amber certainly makes beautiful jewelry, but its clarity and longevity have also proven it to be a great preservation medium. Here are 10 extraordinary fossils that have been found in the solidified resin.

Number 10. Ancient hierarchical civilizations. Thanks to some well-preserved remains, researchers now believe arthropod social structures have been around longer than anyone ever imagined. The encased specimens of ants and termites recently studied date back roughly 100 million years.

Number 9. A possible early version of the bubonic plague. The disease is well known as a Middle Ages mass killer, and its power may have been building since before the dawn of man. Traces of very similar bacteria were found on a 20-million-year-old flea trapped in amber.

Number 8. First carnivorous plant. Dating back some 40 million years, the specimen, which has gooey, insect-trapping tentacles shooting off of its leaves, still contains traces of its last meal. The fossil was found in what is now Russia.

Number 7. 52-million-year-old parasitic beetle. The creature’s prey of choice was ants, and it was somehow able to dupe the hard workers into letting it live in their nest. While there, the beetle would likely eat the ants’ young and exploit their resources.

Number 6. Elusive male stinging scorpion. There are many holes in the history and development of the Miocene scorpion, as very few remains of the ancient ones have been found. Except for this one, a very rare, fully-grown male discovered in Mexico.

Number 5. A daddy long legs with an erect penis. With a 400-million-year history of existence, that the arachnids mate isn’t surprising. However this particular one, estimated to be about 99 million, is the oldest known to have been preserved in such a state.

Number 4. A flower on the verge of being fertilized. Had it not been for the flow of resin that engulfed this bud 100 million or so years ago, the bloom likely would have spread viable seed far and wide. Instead, it was fossilized right as pollen tubes were about to make contact with flower’s stigma.

Number 3. A spider on the brink of an attack. This roughly 110-million-year-old, 8-legged predator missed out on getting a last meal by a sliver of time. The would-be nibble was a wasp that had become ensnared in the web.

Number 2. Dinosaur feathers. Many experts have suggested the prehistoric beasts were covered in them, and this particular piece of amber certainly lends support to the idea. It was discovered in Canada and created some 78 million years ago.

Number 1. Ancient Caribbean lizards. Even though they are 20 million years old, the reptiles inside the golden stones were not found to differ from their contemporary counterparts in any significant way. Scientists attribute the rarity to stable ecological surroundings.

Which amber-encased fossil do you find most fascinating?

From Xinhua news agency in China:

Scientists find earliest intact mushroom fossils

NANJING, March 17 — Paleontologists from China, New Zealand and the United States have found four intact mushroom fossils, sources with the Chinese Academy of Sciences said Friday.

The four, well preserved in Burmese amber for at least 99 million years, are the earliest complete mushroom fossils ever found.

The findings represent four species of mushroom. A stalk and a complete cap containing distinct gills are visible in most of the mushrooms, which are two to three millimeters long.

The research team led by Prof. Huang Diying from Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, reported the finding after researching more than 20,000 pieces of Burmese amber collected over 10 years.

The team also found three kinds of rove beetle, which feed on mushrooms, in pieces of amber 125 million years old. The discovery highlights the palaeo-diversity of mushrooms, pushing back the presence of agaric mushrooms by at least 25 million years.

Mushrooms are common and morphologically diverse fungi. Their bodies are soft and ephemeral and therefore extremely rare in fossils. Until the recent discovery, only five species of mushrooms were known exclusively from amber. Among the previous five species, one was found in a 99-million-year-old piece of damaged Burmese amber, another in a 90-million-year-old piece of New Jersey amber and the three remaining species in 20-million-year-old Dominican amber.
