Specimen PMU 24705 (formerly PMU R233) forms according to Wilson & Upchurch the holotype, descriptive basis, for the species "Euhelopus zdanskyi". It represents one of the skeletons found by Zdansky, named "Exemplar a" by Wiman, who did not formally assign a holotype. This is the original skeleton found by Mertens. Specimen PMU 24705 consists of a partial skeleton with skull and lower jaws comprising these bones: the rostral part of the left nasal; a partial right jugal; the tapered jugal process of the postorbital, partially excavated; the dorsal process of the right quadratojugal; the fragmented left pterygoid (another fragment might be the right splenial, but it is too fragile to be removed from its matrix), a series of twenty-five presacral vertebrae and the left thighbone.
