help John A. Long FAQ
What did John Long discover at the Gogo Formation in Western Australia?
John Long's work on the Late Devonian Gogo Formation has produced spectacularly preserved placoderm fishes in three-dimensional detail. His team described Materpiscis attenboroughi, a placoderm containing a fossilized embryo, which provided the oldest known evidence of live birth in vertebrates.
Where does John Long work as a paleontologist?
John Long is a professor at Flinders University in Adelaide, South Australia. He previously held positions at institutions including the South Australian Museum and has conducted extensive fieldwork on Devonian fossil sites across Australia.
What books has John Long written about prehistoric fishes?
Long has written several popular and academic books, including 'The Rise of Fishes: 500 Million Years of Evolution,' a widely cited overview of fish evolution, and 'The Dawn of the Deed,' which explores prehistoric reproduction based on evidence from the Gogo Formation.
Why was the Materpiscis fossil discovery so significant?
The discovery of Materpiscis attenboroughi, published in Nature in 2008, revealed a fossilized embryo and umbilical cord inside a Late Devonian placoderm fish from the Gogo Formation. This pushed back the known origin of viviparity (live birth) in vertebrates by roughly 200 million years and was named after David Attenborough, who had filmed at the Gogo site.
