SOMETIMES there are remarkable similarities between fossils, revealing
relationships among long-vanished beasts that have left only their bones behind.
Occasionally, those similarities can reveal even more.
While working at the New Mexico Museum of Natural History and Science,
palaeontologist Jerry Harris was researching a paper on the ecology of
the famous feathered dinosaurs of
China鈥檚 Liaoning Province. He spotted a paper describing Hyphalosaurus, a
74-centimetre-long aquatic reptile from the province, in the well-circulated
journal Vertebrata PalAsiatica, and noted it for his project.
Later, when looking through the library of a colleague, he came across a
reprint of a paper published in a much more obscure Chinese journal. It caught
his eye because it had Liaoning in the title, so he began flipping through
it.

鈥淚 came to the long figure of the specimen and recognised it,鈥� Harris
recalls. He then sat down with the other paper, and found the two photos were
mirror images of each other. The bones in one stood proud of the rock surface,
while the other showed depressed casts of the same bones. Both showed a tiny
fish in the same position near the reptile鈥檚 mouth.
Later, he and Josh Smith of the University of Pennsylvania traced the same
pattern of cracks in both photos. Fossils are discovered when a rock is split in
two to reveal bones in one half and impressions in the other, and it seems the
Chinese farmers who uncover most of the Liaoning fossils have realised they can
earn more money by selling the two halves to different buyers.
In this case, they sold the two halves of the Hyphalosaurus fossil to two
different museums in Beijing without telling them about the duplication. So
scientists describing the two discoveries had no idea that they were describing
the same thing.
For the whole story see Smith and Harris鈥檚 report in Journal of Vertebrate
Paleontology (vol 21, p 389).
AMAZING what those clever people at NASA can do. The Associated Press report
on the Genesis mission published on Yahoo! News tells us: 鈥淭he
$259 million Genesis mission will be the first attempt by NASA to return
extraterrestrial samples since the Apollo Moon landings. The spacecraft will
travel to an imaginary point 1 million miles from Earth, where it will orbit for
21 to 22 years and collect atoms of the Sun hurtling by as part of the solar

GOOD news for endangered species, bad news for Hulk Hogan. USA Today reports

SCHOOLKIDS will be jumping up and down all over Britain in two weeks鈥� time.
The Giant Jump, which launches Britain鈥檚 Science Year, will take place on 7
September at 11 am and go straight into The Guinness Book of Records as 鈥渢he
greatest simultaneous jump in history鈥�.
Everyone taking part will jump for one minute, and the results will be
monitored on seismometers and sensing equipment. Although this is the largest
jump that has been attempted, it will not be the first time that people jumping
up and down have caused the ground to shake. Alice Walker, a seismologist at the
British Geological Survey, recalls: 鈥淚n November 1995, Londoners contacted
Scotland Yard claiming they had experienced an earthquake tremor. Investigations
revealed that 20,000 rock fans had been jumping up and down to Oasis in Earl鈥檚
Court, and tremors were being reported from up to one mile away. It will be
interesting to see if hundreds of thousands, and possibly millions of school
students can beat Oasis.鈥�
Science Year, which runs from September 2001 to August 2002, aims to raise
awareness of science among young people aged 10 to 19 years. See
www.scienceyear.com to find out more. If any readers further afield have
seismological equipment, let us know if the tremors caused by the British jump
travel round the world.
THE SPRING issue of Jamba Whirl, the quarterly newsletter from the

WE ASSUME that not many clubbers and ravers received the recent press release
sent out by the Queensland state government about 鈥淓nabling Queensland鈥�, the new

Cool!
IF YOU want to download RipEditBurn MP3 editing software, the RipEditBurn
website asks you: 鈥淧lease choose your nearest download location.鈥� It then offers
you three locations to choose from. These are: 鈥淯SA鈥�, 鈥淯SA鈥� and 鈥淯SA鈥�.
FINALLY, student Sharon Butt spotted this on a noticeboard near a
photocopying room in the electrical engineering building at the University of
New South Wales, Sydney: 鈥淧lease do not remove Room 12GA. Thank you.鈥�
She was happy to comply.
