Three new species of extinct Octopoda discovered in 2009. The species â Keuppia hyperbolaris, Keuppia levante, and Styletoctopus annae â lived about 95 million years ago, and bear a strong resemblance to modern octopuses, suggesting that the Octopoda order has remained relatively unchanged for tens of millions of years. The fossils included evidence of arms, muscles, rows of suckers, ink, and internal gills. The discovery was made by a team led by Dirk Fuchs of the Freie University, which is located at Berlin, Germany. The fossils were found at Hakel and Hadjoula, Lebanon. Various new ammonoid taxa were named, including Ivoites.
A study noting the effects of the KT mass extinction on Earth's modern biota is published.
As science becomes more collaborative, papers with large numbers of authors are becoming more common. To prevent the deformation of the tables, these footnotes list the contributors to papers that erect new genera and have many authors.
