Cheap Beats By
Dre Researchers at the University of Manchester say they have
discovered a 16 million-year-old springtail hitchhiking on the wings of
mayflies. Researchers say that a CT scan of amber has revealed the very first
evidence of any creature hitchhiking on the wings of an adult mayfly. Tiny
springtails are likely using mayflies for transportation today, researchers
note, but this is the first time that this type of activity has been
recorded.
Researchers say that the CT scan showed a small springtail sitting at the
base of one of the mayflys wings.Cheap Beats The
ancient springtail looks to have secured itself to the mayfly via its prehensile
antennae. David Penney and his research team deployed a high resolution CT
scanner to process over 3,000 X-rays from different views. Using cross sections
of the amber, the scientists developed 3D digital images of the springtail.
The images are really impressive. This pioneering approach to studying
fossils has allowed us an insight into the聽behavior聽of one of the worlds most
prevalent organisms,says Mr. Penney.

Cheap After reviewing the 3D digital images of the springtail,
scientists believe that the springtail was trying to leap away from the mayfly
as the amber encased the two creatures (a space of 50 micrometers separated the
two).
The springtails, which scientists say are 1-2 mm long, are found around the
globe in copious numbers. Springtails are able to colonize newly-formed islands
but scientists know very little about how they travel because the springtail
leaps away from danger using its furca on the underside of the abdomen. Their
nervous behavior makes them extremely difficult to observe.
Scientists have evidence of one other case Cheap Dr Dre
Beats of phoresy for springtails. They found five springtails
hooked onto the leg of a harvestman in a聽piece聽of Baltic amber. This is the
first time that phoresy has been recorded in adult mayflies because their
lifespans are very short and their adult lives are dedicated primarily to
reproduction.
I had initially thought the creature on the mayfly may have been a tiny
nymphal pseudoscorpion, as they are known to use other creatures for transport,
and this聽behavior聽is not uncommon to see in amber. I was interested in the fact
that this was the first time a creature had been found on an adult mayfly but I
didnt truly appreciate the significance of my find until I used the CT scanner
and was able to identify the animal as Beats By Dre
Cheap a springtail,says Mr. Penney.
Scientists say that without the amber specimen, observing the behavior of the
mayfly and the springtail would be nearly impossible. The mayfly likely died
instantaneously as the resin flowed over it. Scientists point out that the
mayfly and springtail were unlikely to have been brought together by the resin
flow.

minute details of the animal. We can rotate the image to see parts of the
creature that are obscured when looking from the outside in. In effect, we are
able to digitally dissect the fossil without causing any damage to it
whatsoever. This technology has聽revolutionized聽how we study fossils and the
findings are incredibly exciting,says Mr.
