The oldest harvestmen identified from Germany were 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  The fossils are believed to be round 47-48 million years outdated.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 magazine “Palaeobiodiversity and Palaeoenvironments” the analysis staff describe those arachnids as Leiobunum messelense sp. nov. and Leiobunum schaali sp. nov.

The analysis staff concluded that those “daddy lengthy legs” arachnids have been iridescent.  Iridescent harvestmen nowadays are present in tropical rainforests.  Their discovery within the Messel shale is helping to improve the speculation that within the Eocene this was once a subtropical or tropical wooded area habitat.  Previously, tropical arachnids lived in Germany, most likely they’ll once more because of local weather trade.

The Oldest Harvestmen

Harvestmen (Arachnida: Opiliones) are some of the numerous lineages of arachnids, with greater than 6,700 dwelling species. From the fossil file, about sixty species are identified, the oldest of which works again greater than 410 million years (Early Devonian). Arachnid fossils are uncommon.  Maximum historical harvestman species were recognized from stays preserved in amber.

The Messel Pit close to Darmstadt in Hesse, Germany is without doubt one of the maximum necessary fossil websites in Europe.  Many impressive vertebrate fossils were discovered together with bats, early horses, snakes and primates.  Invertebrate fossils were discovered too.

Now the web site has recorded fossils assigned to the Opiliones Order. The presence of a giant plate protecting a part of the stomach, enabled the analysis staff to assign the fossils to a circle of relatives known as the Sclerosomatidae.  This circle of relatives of harvestmen remains to be discovered within the Northern Hemisphere nowadays.

Iridescent Harvestmen

The fossils have a sparkly, metal look.  It’s most likely that those animals have been in a position to replicate gentle and had iridescent our bodies.  This has no longer been seen prior to in a fossil harvestman specimen.  Iridescent harvestmen are discovered nowadays, however maximum are confined to the tropical forests of southeastern Asia.  The presence of iridescent harvestmen suits the consensus that the Messel Pit represents a former volcanic lake encompass by way of a tropical wooded area.

All the way through the Eocene, tropical arachnids lived in Germany.  Intriguingly, an iridescent harvestman species has been reported in Germany.  It’s idea this species has taken benefit of local weather trade to transport into Europe from its local Africa.
