Discovery of Fossilised Embryo From a Devonian Fish Earns John Long the 2008 Australasian Science Prize. (November 5, 2008)
The
discovery of a fossilised embryo from a Devonian fish has earned Dr John Long,
Head of Sciences at Museum Victoria, the
Australasian Science Prize for 2008.
Dr Long's discovery is not only the first time that a fossil embryo has been
found with an umbilical cord, but it is also the oldest known example of any
creature giving birth to live young. The fossil of a placoderm fish from the
Palaeozoic Era (540-250 million years ago) provides insights into the breeding
behaviour of an entire class of extinct species.
The fossil was found in the Gogo area of north-west Western Australia and has
been named Materpiscis attenboroughi after Sir David Attenborough. Dr
Long says the discovery of the original "mother fish" was the "rosetta stone
that opened our minds to interpreting other fossils" whose embryos were less
clearly recognisable.
Long's awarding of the 2008 Australasian Science Prize drew support
from a number of prominent researchers. Prof Pat Vickers-Rich, Chair of
Palaeontology at Monash University, described Long's work as "world-class. Not
only did this take very serious and clever field work, but the delicate
preparation of this specimen and the recognition of what was before one's eyes
was just outstanding."
Ken Campbell, Emeritus Professor of Geology at the Australian National
University, said that "John Long has the wonderful ability to sort through new
material and see structures that other experienced palaeontologists completely
overlook," and praised "his capacity to make unusual observation, his capacity
to extract information from unlikely sources and his capacity to interpret new
data in terms of a good knowledge of comparative anatomy".
Lyn Beazley, Professor of Zoology at the University of Western Australia,
praised Long's "outstanding science and science communication work, which has
increased enormously our understanding of vertebrate evolution. Without doubt
John is an outstanding scientist and an outstanding citizen."
Long believes the award is a "shot in the arm for palaeontology," and "shows
palaeontology still has a major role to play in bioscience, despite the rise of
molecular biology. These fossils give you an exact timing, which can tie the
molecular clock to actual events in evolution."
Long also considers the Prize "a fantastic recognition of the way museums are
doing high quality science". He says that museums can "do more fundamental
research that is not driven by economically-oriented research priorities. We
need to keep collecting more fossils because you never know what you might
find."
