In 1874, extensive remains of what was clearly a large herbivore equipped with spikes were uncovered in England; the first partial stegosaurian skeleton known. They were named "Omosaurus" by Richard Owen in 1875. Later, this name was shown to be preoccupied by the phytosaur "Omosaurus" and the stegosaurian was renamed "Dacentrurus". Other English nineteenth century and early twentieth century finds would be assigned to "Omosaurus"; later they would, together with French fossils, be partly renamed "Lexovisaurus" and "Loricatosaurus". None of these specimens was complete though, and even together they could not have provided a good understanding of stegosaurian build. Owen e.g., initially assumed that the spikes were placed on the wrists. However, very soon after the discovery of "Omosaurus", American finds would fully compensate for this.
