Palanasaspis chekhivensis is an extinct species of pteraspidid heterostracan agnathan which existed during the early Devonian period of Podolia, Ukraine. It is known primarily from a wide rostral plate, which is referenced in the generic name, a compound word combining the Latin words pala, "shovel," and nasus, "nose," with the Greek suffix aspis, "a small shield." Although the rostral plate clearly marks the creature as a pteraspidoid heterostracan, that literally nothing else of its anatomy is known forces researchers to leave it as incertae sedis.[1]
