Fossil Friday: Helicoprion

Helicoprion is an extinct genus of shark-like, cartilaginous fish that lived from the early Permian (~290 m.y. ago) all through to the massive Permian-Triassic extinction episode (roughly 250 m.y. ago.)

Live fast, die young: the secret to surviving a mass extinction

Drastically reducing body size and, maybe most importantly, lifespan may have been the most important course of action evolution undertook to preserve some species, paleontologists argue.

Europe might lose its ash trees forever

Europe is likely to lose all its ash trees, the largest-ever survey of the species warns. Plagued by both a fungal disease known as ash-dieback and an invasive species of beetle, the emerald ash borer, the tree might be wiped clean off of the continent.

Many species now going extinct may vanish without a fossil trace

We judge our planet’s biological past by using geological evidence – fossils. Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past.

It pays to be a small fish in a big pond after a mass extintion

Some 360 million years ago, the oceans were teeming with big fish, some as big as a school bus. Then something terrible happened, the causes of which still escape scientists today: the Hangenberg Event. This was the last peak in a streak of mass extinctions known as the Late Devonian extinction which exterminated 97% of all marine vertebrate species. In the aftermath, it paid to be small a new study suggests. The researchers at University of Pennsylvania found that small fish dominated the ecological niches for nearly 40 million years. This tremendous rebound time is relevant today when overfishing is threatening countless large fish species. Once these disappear, it might be a very long time before we get tuna-sized fish back on our plates.
