Overview
- Researchers published the formal description of Panthera pardus burgtonnae in June 2026 after reexamining fossils recovered in the 1990s from travertine at Burgtonna, Thuringia.
- The fossil set includes a right lower jaw with teeth, an upper carnassial and limb bones that likely come from a single, relatively young individual found 4.4–5.3 metres deep.
- Distinct dental traits—a narrow, low first lower molar paired with a broad front tooth—and a robust postcranial skeleton are the primary features used to define the new subspecies.
- Authors estimated body mass at about 35–40 kg using a newly introduced body‑mass index that relates weight to head–body length, showing a compact, heavy build compared with many modern leopards.
- The find expands evidence for multiple, regionally distinct leopard lineages in late Middle Pleistocene Europe and raises a testable hypothesis of past gene flow with other large felids that will require well‑preserved genomes to confirm.
