Remnants of long-gone lifeforms, which have been preserved despite all the changes that have taken place in the rocks, show that the stone underlying the municipality is made up of marine deposits from the Lower Devonian.

The fossils come from the Devonian Sea, as geologists call it, which covered not only the Eifel but also broad areas of Central Europe too, roughly 400 to 340 million years ago.

Several lava flows and a dried-up maar kettle to the right of the road on the way to Üdersdorf bear witness to volcanic activity many millennia ago.

Forty-four years later, in 1698, as can be seen in a tenancy agreement, there were four Electoral estates at Oberstadtfeld: the Achterhof, the Hühnerhof, the Hundswinklerhof and the Heinenhof.

In 1794, the Eifel passed to France and was in the new Department of Sarre, and beginning in 1803, Oberstadtfeld was part of the parish of Niederstadtfeld in the Diocese of Trier.

Great parts of Oberstadtfeld were destroyed in the early 20th century when 17 houses along with stables and barns were lost to a fire.

The municipality's arms might in English heraldic language be described thus: A bend indented azure between argent a barn with roof sable and Or fire gules.

The barn on the dexter (armsbearer's right, viewer's left) side is meant to refer to the four Electoral estates at Oberstadtfeld, the Achterhof, the Hühnerhof, the Hundswinklerhof and the Heinenhof.
