A 290-million-year-old fossil forest is discovered by an investigation team in the state of Parana, southern Brazil.
It is a group of 164 logs of 'lycophytes' (without fruits, flowers and seeds) of an extinct variety, whose upright position preserved over time is considered a rare occurrence.
The Paraná forest was found at the end of 2018, when a road was opened in the area to give access to an industrial plant. Geologists went to the site to study the exposed rocks, but to their surprise they found this fossil forest.
There were only two other similar findings in the southern hemisphere, but of smaller dimensions, in the Brazilian state of Rio Grande do Sul (south) and in Argentinean Patagonia.
