"INVISIBLE" Ancient Bugs Discovered By Hi-Tech X-Ray

This ancient fly, dubbed Trichomyia lengleti, is one of a handful of bugs added to a new online database of "digital fossils." 

Paleontologists from the European Synchrotron Research Facility in France used high-energy x-rays to peer inside 640 pieces of opaque, fossilized amber that date to the Cretaceous period, 145 to 65 million years ago.

The fossils were found in 2008 in from the Charentes region of southwestern France. Until recently, fossils inside opaque amber were invisible to paleontologists. But the new accelerator technology revealed unprecedented views of 350 previously invisible insects, animals, and plantswhich could previously only be studied from fossilized mud imprints.

Using x-rays for paleontology is a new and important technique for seeing inside fossils that you can't cut or break open, said researcher Paul Tafforeau.

"When we are dealing with fossils we have to study them, but we also have to preserve them."

You won't find this cockroach crawling around city apartments--It scurried across the earth around 60 million years ago.

But now x-ray radiation has revealed the prehistoric critter frozen inside a piece of opaque amber. 

The cockroach was added to a new online database of digital fossils, which have become a new area of study in archaeology and taxonomy.

A hundred-million-year-old spider (above) is seen buried inside a tomb of opaque amber.

The digital fossil--a combination of multiple x-rays--was recently added to a new online database compiled by French researchers.

A hundred-million-year-old millipede ancestor encased in amber (pictured) was recently imaged by researchers from the European Synchrotron Research Facility.

Using a high-resolution scan called microtomography, researchers pinpointed finely detailed body parts, such as bristles, tiny legs, and insect wings--and even the hairs on the one-millimeter-long millipede.

In just 48 hours of imaging with a particle accelerator, researchers found more than 350 previously invisible creepy crawlies from Cretaceous-period amber (above right). 

Cracks and imperfections often show up in x-rays of amber (above, top left), posing a challenge to paleontologists who want to see the amber's contents. 

But a research team at the European Synchrotron Research Facility found that soaking amber in water fills in cracks, allowing for much clearer views of the insects (top, bottom left).

This prehistoric wasp-like insect, called Hymenopteran falciformicidae, was recently revealed by new x-ray technology. 

European researchers are investigating innovative ways to visualize these digital fossils, such as 3D physical models and glass blocks with the a print of the specimen inside.

This hundred-million year old isopod crustacean--an aquatic relative of woodlice--was one of more than 350 insect fossils found hiding in chunks of amber.

The critter was added to the European Synchrotron Research Facility's new online database of "digital fossils," which is accessible to the public.

World's Best Creative Butterflies By Jo Whaley











Jo Whaley has lifelong roots in the San Francisco Bay Area, having earned advanced degrees in Art and Photography from the University of California, Berkeley by 1980. Whaley originally studied to become a painter, putting her abilities to work as a scenic artist for the San Francisco Opera and other Bay Area theatrical companies. Her theater experience openly informs her photography, in which she creates stage sets and employs numerous props, painted backdrops and dramatic lighting. All of her photographic series fuse the language of photography with the language of painting and rely on an expressive use of color.

Working in discreet series, the subject matter of her photographs over the last 25 years have ranged from allegorical nudes, to a revision of the "vanitas" still life tradition, to a fusion of natural history and environmental issues in the Entomology Portfolio of insects. The compelling issue, that has driven her work, is the interface between nature and urban technological culture. With an ironic and quirky point of view, she juxtaposes organic and manmade elements to reflect the issue of environmental degradation in an imaginative manner.


Since the early 1980’s Whaley’s photographs have been exhibited in the United States, Europe and Japan. Between 1989 and 1993 Whaley received numerous grants to work with the Polaroid 20x24 camera in New York and received one of the last National Endowment Visual Artists Fellowships in 1994. She taught at various Universities from 1983-2003. She is married to the photographer Greg Mac Gregor and they divide their time between Santa Fe, New Mexico and Oakland, California.
