Außergewöhnlich seltene Fossilplatte mit zwei Exemplaren – Museumsqualität. - Tierfossil - Chunerpeton tianyiensis - 40 cm - 30 cm

Extremely Rare Dual-Specimen Fossil Plate: Giant Adult & Sub-adult "Prehistoric Giant Salamander" (Chunerpeton tianyiensis) - 28 cm & 15 cm - Museum Quality - Yanliao Biota, China

Locality : Liaoning Province, Northeast China (from the famous Yanliao Biota / Daohugou Beds)
Geological Age : Late Jurassic (Mesozoic era, approximately 160–165 million years old)

Overview: An exceptional, museum-quality catastrophic mass mortality plate featuring two beautifully preserved individuals of the exact same species: the prehistoric giant salamander, Chunerpeton tianyiensis, from the Mesozoic deposits of Liaoning, China. This extraordinary single slab preserves an incredibly rare ontogenetic growth series (developmental sequence) of the earliest known member of the Cryptobranchoidea (the lineage of modern giant salamanders and Hellbenders). It showcases a massive, fully mature adult measuring 28 cm alongside a 15 cm sub-adult/juvenile.Palaeo-Ecological & Scientific Significance

(Paleoecological and scientific significance) Chunerpeton tianyiensis is a crucial evolutionary link, with the large 28 cm individual representing an exceptionally rare maximum size for this species. This plate provides definitive evidence of the gregarious (grouping) behavior of these ancient predators. It captures a sudden, tragic volcanic event that preserved a family group in mid-Mesozoic time. Anatomical Highlights & Preservation

(Anatomical Highlights and Preservation)3D Preservation: Exceptionally detailed specimens featuring strong, mineralized, reddish-brown and black bones.28 cm Mature Adult: Features the wide, parabolic, "broad face" skull characteristic of Chunerpeton tianyiensis.15 cm Sub-Adult: Perfectly articulated with clear skull, soft tissue shadows, and detailed, outstretched limbs.
