Designation

Fossilized Fern Frond (Neuropteris sp.)

Description

This specimen is a fossilized section of a fern-like frond preserved in a dark, fine-grained sedimentary matrix, likely carbonaceous shale. The primary side of the slab features a well-defined rachis with several pairs of pinnules (leaflets). The pinnules are approximately 1-1.5 cm in length, possessing an elongated oval shape with rounded apices and a slightly cordate base where they meet the stem. The preservation is a light-colored compression fossil, creating a sharp visual contrast against the black rock. The reverse side of the matrix shows smaller, fragmented plant impressions, indicating the specimen was part of a fossil-rich bedding plane. The rock itself is an irregular, tabular fragment with natural fracture surfaces and visible layering (lamination) consistent with sedimentary deposition in a low-energy environment, such as a Carboniferous swamp. There are no signs of artificial restoration; the fossil was exposed through the natural splitting of the stone along its cleavage plane.
