The oldest harvestmen recognized from Germany have been described. That is the primary formal description of fossil harvestmen from the Eocene.  The newly described harvestmen (Arachnida: Opiliones), come from the well-known Messel Pit fossil deposit.  The fossils are believed to be round 47-48 million years outdated.  Writing within the journal “Palaeobiodiversity and Palaeoenvironments” the analysis crew describe these arachnids as Leiobunum messelense sp. nov. and Leiobunum schaali sp. nov.

The analysis crew concluded that these “daddy lengthy legs” arachnids have been iridescent.  Iridescent harvestmen at present are present in tropical rainforests.  Their discovery within the Messel shale helps to help the speculation that within the Eocene this was a subtropical or tropical forest habitat.  Previously, tropical arachnids lived in Germany, maybe they’ll once more because of local weather change.

The Oldest Harvestmen

Harvestmen (Arachnida: Opiliones) are one of the vital numerous lineages of arachnids, with greater than 6,700 residing species. From the fossil document, about sixty species are recognized, the oldest of which works again greater than 410 million years (Early Devonian). Arachnid fossils are uncommon.  Most historic harvestman species have been recognized from stays preserved in amber.

The Messel Pit close to Darmstadt in Hesse, Germany is likely one of the most essential fossil websites in Europe.  Many spectacular vertebrate fossils have been discovered together with bats, early horses, snakes and primates.  Invertebrate fossils have been discovered too.

Now the location has recorded fossils assigned to the Opiliones Order. The presence of a giant plate protecting a part of the stomach, enabled the analysis crew to assign the fossils to a household referred to as the Sclerosomatidae.  This household of harvestmen remains to be discovered within the Northern Hemisphere at present.

Iridescent Harvestmen

The fossils have a shiny, metallic look.  It’s seemingly that these animals have been capable of mirror gentle and had iridescent our bodies.  This has not been noticed earlier than in a fossil harvestman specimen.  Iridescent harvestmen are discovered at present, however most are confined to the tropical forests of southeastern Asia.  The presence of iridescent harvestmen matches the consensus that the Messel Pit represents a former volcanic lake encompass by a tropical forest.

Through the Eocene, tropical arachnids lived in Germany.  Intriguingly, an iridescent harvestman species has been reported in Germany.  It’s thought this species has taken benefit of local weather change to maneuver into Europe from its native Africa.
