This beautiful fossil is from the Green River in Colorado, and is a cricket from approximately 50 million years ago. The matrix which holds it is like a porcelain shale. This is an extremely rare fossil, and you just don't see many of them. I used a ginkgo leaf because the ginkgo is the oldest tree in the world right now. The cricket looks much the same as crickets look today. It hangs from a wonderful little twig that is electroplated with copper, and a real ginkgo leaf, both from the Ukrain. The Septarian is from Morocco. The wire art is copper as is the hand woven Viking Knit chain. The bezel of the fossil stone is hand-woven copper wire.
The fossil pendant including the bail and the leaf is 1.99 x 2.6" , the septarian is 1.9 x 2.08" including the bail. It is very light weight with the whole piece including the chain is only 3.5 oz.
This piece is not only a collector's item it brags excellent composition, texture and color. It is all live from Mother earth as it grew there.
SCIENCE & MYTH
Crickets make a big contribution to the sounds of a summer night. And they’ve been doing so for some 165 million years. Now paleontologists have reconstructed the song of a long-extinct bushcricket—based on its remains.
The researchers got hold of a bushcricket fossil from the Jurassic period with well preserved wings. Even the stridulating organs, which insects rub together to make noise, were visible, which allowed researchers to compare the extinct cricket to 59 living species.
The scientists concluded that the crickets produced single frequencies in short bursts. And based on physiology and the comparisons, they estimated the pitch and length of each note that the ancient species sang.
The study is in the Proceedings of the National Academy of Sciences. [Jun-Jie Gu et al., "Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females"]
This work shows that the anatomy to make music had already evolved over a hundred million years ago. Like modern bushcricket species, the ancient male crickets probably sang to advertise their presence and reproductive quality to potential mates. As a bonus, they’ve helped us know a bit about the sound of their long-lost world.

50-million-year-old cricket and katydid fossils from Colorado hint at origin of insect hearing

How did insects get their hearing? A new study of 50-million-year-old cricket and katydid fossils sporting some of the best preserved fossil insect ears described to date are helping to trace the evolution of the insect ear.
According to paleontologist Dena Smith of the University of Colorado Boulder's Museum of Natural History and University of Illinois Professor Roy Plotnick, who collaborated on the new study at the National Evolutionary Synthesis Center, or NESCent, in Durham, N.C., insects hear with help from some very unusual ears.
Grasshoppers have ears on their abdomens. Lacewings have ears on their wings. The ears of the tachinid fly are tucked under the chin. "Insects have ears on pretty much every part of their body except on their head proper," Plotnick said.
Insects have evolved ears at least 17 times in different lineages, said Smith, also an assistant professor in CU-Boulder's geological sciences department. Smith and Plotnick are trying to figure out when different insects got their ears, and whether predators may have played a role.
Modern insects use their ears to tune in to each other's chirps, trills and peeps. Think of the chorus of crickets, or the love songs of cicadas. But many species can also pick up sounds beyond the range of human hearing, such as the high-pitched sonar of night-hunting bats, according to Smith and Plotnick.
Crickets, moths and other flying insects have ultrasound-sensitive hearing and can hear bats coming, diving or swerving in midflight to avoid being eaten. Insects that evolved such supersensitive hearing would have had a crucial survival advantage, the researchers said.
"The big evolutionary trigger for the appearance of hearing in many insects is thought to be the appearance of bats," Plotnick said. "Prior to the evolution of bats we would expect to find ears in relatively few insects, but after that we should see ears in more insect groups," he explained.
Did insect ears get an upgrade when bats came to be? Before this study the fossil evidence for insect hearing was too poorly preserved or scantily described to know for sure, according to the researchers.
To find out, Plotnick and Smith turned to remarkably well-preserved fossils from a series of lake deposits in Wyoming, Utah and Colorado known as the Green River Formation, where some of the earliest bats are found.
Roughly 50 million years ago, fine-grained sediment covered and buried the animals that lived there and managed to preserve them in exquisite detail. "You can see every tiny feature down to the veins in their wings and the hairs on their legs," said Smith, who has been studying Green River fossils for more than 15 years.
For this study, the researchers examined fossils from a Green River site in Colorado, focusing on crickets and katydids, which have ears on their front legs, just below their knees.
The team scoured more than 500 museum drawers of Green River fossils for crickets and katydids with intact front legs, looking for evidence of ears. "You can just make them out with the naked eye," Plotnick said. "They look like the eye of a needle."
In crickets and katydids living today, the ear is a tiny oval cavity with a thin membrane stretched over it that vibrates in response to sound, much like our own eardrum.
The fossil ears measured half a millimeter in length, and were virtually identical in size, shape and position to their modern counterparts. The findings suggest that this group of insects evolved their supersensitive ultrasonic hearing long before bat predators came to be, the researchers say. "Their bat-detecting abilities may have simply become apparent later," Smith said. "The next step is to look for ears in other insect groups."
According to Native traditions:
If Cricket has jumped across your path;
It is a sign of extreme good luck. All the things that you have been working toward and dreaming about are now possible. Stay open to guidance and cosmic messages and you will know exactly what you have to do. Whether its buying a lottery ticket, interviewing for a new job, or being in the right place at the right time. All things are possible right now – all you have to do is feel that you deserve it!
If Cricket is your Animal Totem;
You know how to sing your song loud and clear! You love to use the power of your own voice in order to attract what you want and need in life and you have a gift for finding your way through difficult moments with panache and aplomb. You are an excellent communicator, love to walk your talk and are often vegetarian. You understand the power of music and will often have a career that uses music as a form of healing. You are a whirlwind of action, a blur of movement, and always on the go. You seem to have a hard time staying in one place and are always jumping off in one direction or another.
If Cricket has come into your Dream;
If you see crickets in your dream it usually represents introspection. Look inward for your answers or to release old emotional baggage. You are seeking guidance in the resolution of a current impasse. If you hear crickets in your dream it can suggest that you are allowing minor things to bother you. Go inward to find the true irritation to resolve it. If the cricket is leaping – know that you are moving forward spiritually in leaps and bounds right now.
Whether the effects of stones and crystals such as this are real or merely a placebo effect is unknown. All we know for certain is that the use of gemstones in healing goes back centuries. And we know that modern science has discovered some surprising applications for the unique properties of certain crystals as all stones and crystals are made up of the same things that make up our bodies!
