Noeggerathiopsis hislopi

Overview

Noeggerathiopsis hislopi introduces a Permian plant through its leaves. Veins running parallel along an elongated leaf before forking in two draw attention. The outline and pattern of a single leaf provide clues to an ancient plant.^[1]

Key facts

Several veins begin at the base and run straight upward, frequently forking along the way. Although they look like parallel lines, following them closely reveals an increasing number of branches. Such vein branching, as well as the outer outline, helps distinguish plants.^[1]

Time and place

This material is an Early Permian plant fossil. It came from the Barakar Formation in the Umrer Coalfield of the Wardha Basin, present-day Maharashtra, India. The researchers examined leaves from the upper seam of the Makardhokra opencast mine together with those from the middle seam of the Umrer opencast mine.^[1]

The time range describes source context, not the complete duration of this species.

Size, form and skeleton

The leaves range between elongated lance-shaped and spatula-shaped forms, with rounded tips and narrowing bases. Their margins are untoothed. The leaves described in the study are 56–164 mm long and 15–30 mm wide.^[1]

Habitat and reproduction

The Umrer fossil flora contains abundant Glossopteris leaves alongside those of Noeggerathiopsis. Comparing traces of several plants from one coalfield reveals the diversity of the ancient flora. The coal seams containing these leaves provide the geological setting for that comparison.^[1]

Fossil discovery

A 2012 study presented 20 specimens, including complete leaves and fragments. The researchers explained that leaf shapes and venation agreed well with illustrations published by Feistmantel in 1879. Comparing old illustrations with newly documented fossils confirmed features of the same plant.^[1]

Research questions

The researchers also compared these leaves with Noeggerathiopsis from other regions. Distinct stomatal grooves between veins, seen in permineralized Middle Permian leaves from Antarctica, were not identified in this material. Even similar leaves reveal different features when their preserved surfaces are compared.^[1]

Observation

The representative magnet repeats the same reconstruction motif in a decorative arrangement. Grouping and spacing are artistic; the description below concerns each source motif. The illustration is an interpretation focused on the overall outline of a single leaf. Move your gaze from its narrowing base to the rounded tip, then find the parallel veins and their branching points in between. Follow the leaf features preserved in the fossil for a closer view of an ancient plant.^[1]
