Discovery and naming

The first fossil specimens of Khatyspytia were found from the Khatyspyt Formation of the Khorbusuonka Group in Siberia, [1] and formally described and named in 1985. [2]

The generic name Khatyspytia derives from the Latinised place name of the Khatyspyt Formation, from where the first fossils were found. The generic name grandis directly derives from the Latin word of the same spelling, "grandis", to mean "large". [2]

Description

Khatyspytia grandis is a tall, frondose organism, reaching up to 24 cm (9.4 in) in height. It has a notably elongated stalk, with a relatively slender frond, and a wide holdfast structure. [2]

It has been compared to Charniodiscus , another arboreomorph, [1] with some papers suggesting it to be a junior synonym of the species C. procerus, [3] although nothing has been properly published on this matter. [4]
