Let’s talk about #massextinctions:
The first animals evolved around 600 million years ago. While balance is usually maintained between extinctions and the evolution of new species, there have been six major events where the rate of extinction has drastically spiked.
The first animals evolved around 600 million years ago. While balance is usually maintained between extinctions and the evolution of new species, there have been six major events where the rate of extinction has drastically spiked.
In some cases entire groups of animals have disappeared from existence. These are known as ‘mass extinction events’.
While we will never be able to know exactly what happened all of those millions of years ago, these extreme events can help us to better understand the impacts of human-driven environmental changes that are occurring in modern times.
Last week my first first author paper was published, and also my first plant genus and species description! We described Keraphyton mawsoniae, a new fern-like plant from the Late Devonian of Australia. I wrote a little thread about it for #FossilFriday #Palaeobotany #Paleontology 
Our paper is available online #openaccess at peerj.com/articles/9321/ “Keraphyton gen. nov., a new Late Devonian #fern-like plant from Australia” #paleobotany #paleontology #plant #taxonomy (2/17)
The #fossil #plant was first discovered by an amateur geologist on the bank of the Manilla River in Barraba #NewSouthWales… more than 50 years ago #NSW (3/17)
