Characteristics
Characteristic for the culture are the inhumations in kurgans (tumuli) in pit graves with the dead body placed in a supine position with bent knees. The bodies were covered in ochre. Multiple graves have been found in these kurgans, often as later insertions.
Significantly, animal grave offerings were made (cattle, sheep, goats and horse), a feature associated with Proto-Indo-Europeans (including Proto-Indo-Iranians).
The earliest remains in Eastern Europe of a wheeled cart were found in the "Storozhova mohyla" kurgan (Dnipropetrovsk, Ukraine, excavated by Trenozhkin A.I.) associated with the Yamna culture.
