Dinomischus is an enigmatic animal from the Cambrian period.


Dinomischus loosely resembled a flower, growing approximately 20 millimeters in height.[1] A long, thin stalk attached its cup-shaped body to the sea floor. The "petals" around the mouth likely gathered food particles.[2]


The classification of Dinomischus is still uncertain, although similar organisms include the modern entoprocts.[3]


The first specimen of Dinomischus was discovered by Charles Doolittle Walcott in the Burgess Shale, but it was not until 1977 when it was fully described by Simon Conway Morris.[4] Further specimens have since been discovered in Chengjiang and Guizhou, China.[5]
