Plagiopetalus

Plagiopetalus is an extinct genus of wasps that lived during the Early Cretaceous period, around 145-100 million years ago. The name Plagiopetalus comes from the Greek words "plagios," meaning "oblique," and "petalon," meaning "petal," in reference to the obliquely arranged petals of its flowers. This reference pertains to its feeding behavior on nectar, collected using its elongated proboscis.

The Plagiopetalus genus consists of two described species: P. convexus and P. nicholsoni. They were characterized by their long, slender bodies, typically with an approximate length of 1-2 centimeters. Their six legs and elongated wings were well-suited for flight. For pollination and nectar collection purposes, they likely visited a variety of flowers with different shapes, sizes, and colors.

Like modern wasp-like insects like Hymenoptera, Plagiopetalus are often found in high-organic matter-rich sedimentary layers that contain associated plant debris, indicating a feeding habit in pollination roles. Incidentally, their placement in the fossil record demonstrates a transition between the extinct Mesozoic germ group including the wasps had a series of nearest dead relatives within the history timeline.

Geographical records show a comprehensive diversity across Asia and North America. Their fossilized remains, typically discovered in Burmeseamber and certain other types of Mesozoic formations has maybe been found in alliance with commonly indoor parasites as traffic elements. The actual availability of Plagiopetalus and closely connects all vary systematically as classification tool references.
