Latest Placodermi Stories
According to a new study in the journal Nature, a team of international researchers has found the earliest-known organism to reproduce by sexual intercourse, a small bony fish known as Microbrachius dicki.
A study published on Wednesday in the journal Nature has revealed new details on the evolution of the jaw – a major defining structure in the evolution of the face.
Swedish, Australian and French researchers present for the first time miraculously preserved musculature of 380 million year old armored fish discovered in north-west Australia.
The famous fossil fish species Tiktaalik roseae lived in the brutal Devonian environment 375 million years ago and is receiving scientific acclaim for providing some of the best evidence to date of the evolutionary change from lobe-finned fish to four-limbed animals.
It’s likely the question “how long have humans had teeth?” has never entered into many normal and sober minds. Scientists and, more specifically, odontologists, are a different breed, however, and have wondered about the origins of teeth for many years.
More than 99 per cent of modern vertebrates (animals with a backbone, including humans) have jaws, yet 420 million years ago, jawless, toothless armour-plated fishes dominated the seas, lakes, and rivers.
A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity.
The mode of reproduction seen in modern sharks is nearly 400 million years old. That is the conclusion drawn by Professor Per Erik Ahlberg, Uppsala University, from his discovery of a so-called "clasper" in a primitive fossil fish earlier this year. The research results are published today in Nature.
New research published Wednesday shows that sex has been around for much longer than many scientists had previously believed, with internal fertilization prevalent among prehistoric fish living on tropical reefs during the Devonian period 380 million years ago.
Scientists in Australia reported Thursday they had discovered the remains of the oldest vertebrate mother ever found. The fossilized 375-million-year-old placoderm fish was found in the Gogo area of northwest Australia.
