Prähistorische Fossilienjagd auf der Farm – Erkunden Sie die Jura-Meereswelt auf einem Bauernfeld

Eine außergewöhnliche prähistorische Stätte mit den Überresten von Tieren, die in einem tropischen Meer lebten, wurde auf einem Bauernfeld in Gloucestershire, England, entdeckt.

Die Fossilien wurden unter einem Feld ausgegraben, das von einer alten Rasse englischer Longhorn-Kühe genährt wurde, und sie sind überraschend gut erhalten. Obwohl es etwa 183 Millionen Jahre alt ist, sehen die Fossilien aus, als wären sie in der Zeit eingefroren worden.

Die Überreste von Fischen, alten Meeresreptilien, Tintenfischen, seltenen Insekten und mehr, die in 3D-konserviertem Kalksteinbeton enthalten sind, wurden zum ersten Mal von einem Team von Paläontologen ausgegraben. Die Fossilien stammen aus einer inneren Gesteinsschicht, die zuletzt vor mehr als 100 Jahren in Großbritannien freigelegt wurde. Es stellt eine einzigartige Gelegenheit dar, Fossilien aus einer Zeit zu sammeln, als dieser Teil des Landes tief unter Wasser stand.

Der neu gefundene Standort befindet sich auf der Court Farm in Kings Stanley in der Nähe von Stroud, Gloucestershire. Es wurde von Sally und Neville Hollingworth, begeisterten Fossiliensammlern, entdeckt. Sie entdeckten kürzlich Mammutreste im nahe gelegenen Cotswold Water Park, eine Entdeckung, die in einer BBC One-Dokumentation gezeigt wurde.Attenborough und Mammoth CemeteryIm Jahr 2021.

Sally und Neville erklärten: „Diese Fossilien stammen von Anfang an[{“ attribute=““>Jurassic, specifically a time called the Toarcian. The clay layers exposed at this site near Stroud have yielded a significant number of well-preserved marine vertebrate fossils that are comparable to the famous and exquisitely preserved similar fauna of the Strawberry Bank Lagerstätte from Ilminster, Somerset – a prehistoric site of exceptional fossil preservation. Excavations at Kings Stanley over the last week have revealed a rich source of fossil material, particularly from a rare layer of rock that has not been exposed since the late 19^th Century.”

Dr. Dean Lomax, a paleontologist and a Visiting Scientist at The University of Manchester, who recently led the excavation of the Rutland ichthyosaur that also dates to the Toarcian geological age, was part of the team and said: “The site is quite remarkable, with numerous beautifully preserved fossils of ancient animals that once lived in a Jurassic sea that covered this part of the UK during the Jurassic. Inland locations with fossils like this are rare in the UK. The fossils we have collected will surely form the basis of research projects for years to come.”

Many of the specimens collected will be donated to the local Museum in the Park, Stroud, where they will form a significant part of the museum’s paleontology collections. One of the team members, Alexia Clark, who is the museum’s Documentation and Collections Officer said: “We’re excited to expand our knowledge of the geology of the Stroud District and we are looking forward to a time when we can share these amazing finds with our members and visitors. Being part of the excavation team has been a real privilege and I can’t wait to share details of that experience through our members’ newsletter.”

Among the best finds were several fossil fish with excellent details of their scales, fins, and even their eyeballs. One of the most impressive discoveries was a three-dimensionally preserved fish head, belonging to a type of Jurassic fish called Pachycormus. The fish looks as if it is ‘leaping off the rock’ that it was contained inside. A digital 3D model of this fossil has been created by Steven Dey of ThinkSee3D.

Field observations and preparation of the fauna found so far indicate that the Court Farm fossils were rapidly buried, as suggested by the absence of any encrusting animals or burrows in the sediment. The layered concretions around the skeletons formed relatively early before the sediments were compacted, as the original sediment layering is preserved. These concretions prevented further compaction and compression from the overlying sediments during burial and thus preserved the fossils in three-dimensional time capsules.

Neville added, “Using the latest fossil preparation and imaging techniques to understand this unique fauna in more detail will create a rich repository. Also, we will leave a permanent reference section after excavations have concluded. Given the location and enthusiasm from the landowner and local community to be involved it is hoped to plan and develop a local STEM enrichment program as there will be opportunities for community groups and local schools to be involved in the research, particularly from the Stroud area with a focus of targeting audiences in areas of low STEM capital.”

The landowner, Adam Knight, said: “I’m delighted that after the initial work that Sally and Nev did over three years ago we now have a full-scale dig on the farm involving a range of fossil experts from The Natural History Museum, The University of Manchester, University of Reading and The Open University. On Friday we were also joined by Emily Baldry (16) on a day’s work experience before she goes to University to study paleontology – it’s wonderful to see her enthusiasm for her chosen profession. It has been a real pleasure to host the dig and I’m excited to see the results of what has been found.”

The team of paleontologists is very grateful to the Geologists’ Association Curry Fund for financing the excavation phase. Going forward, the team will continue to analyze the specimens and publish their research with the fossils planned for display at Museum in the Park, Stroud, and at the Boho Bakery Café at Court Farm, Kings Stanley, Gloucestershire.
