Sirilorica is a monospecific genus of stem-group scalidophoran from the Sirius Passet.[1]

Morphology

Sirilorica was a worm-like animal ranging from three to eight centimetres in length.[1]

Ecology

Sirilorica probably burrowed on the sediment surface, although since it is never preserved alongside burrows the fossils were presumably washed to their final resting places.[1]

Affinity

The loricate plates align the animal with the loricates and their sister group the priapulids (which have loricae during their juvenile stages).[1]

Etymology

Its generic name reflects its origin in the Sirius passet, and its loricate appearance. Its specific epithet honours the Carlsberg Foundation's financial contribution to Sirius Passet research.[1]
