Quadratapora

Quadratapora is a genus of lobopodian known only from its biomineralized dorsal plates, which somewhat resemble those of Microdictyon.^[1] Q. tenuiporatum is known from a single specimen that was initially described as dating to the Tommotian, representing (perhaps along with Rhombocorniculum)^[2] the earliest record of lobopodians.^[1] However, the material is now thought to be Atdabainan in age, reflecting both a mistake in the initial description of the material^[3] and a revision of the stratigraphy of the Isit section on the Lena river,^[4] from where the single specimen heralds. Q. zhenbaensis is Atdabanian in age.
