Vetulicola rectangulata (meaning "rectangular ancient dweller") is a species of extinct animal from the Early

Chengjiang biota of China. Regarded as a deuterostome
, it has characteristic rectangular anterior body on which the posterior tail region is attached. It was described by Luo Huilin and Hu Shi-xue in 1999.

Description

Size comparison

V. rectangulata was described by Luo Huilin and Hu Shi-xue of the Yunnan Institute of Biological Science in 1999.[1][2] The fossils were discovered from the Early Cambrian Chengjiang deposits in Kunming region, Yunnan, China.[3]

Like V. cuneata, V. rectangulata has a body composed of two distinct parts of approximately equal length. The anterior part is oval to rectangular in shape,

dorsally. Paired openings connecting the pharynx to the outside run down the sides. These features are interpreted as possible primitive gill slits.[5] Vetulicola rectangulata could be up to 7.2 cm long, and up to 3.7 cm in height (most specimens being 3.6 cm high).[6]

Lifestyle

It is assumed that V. rectangulata spent most or all of its time swimming in the water column. Sediment found within the gut suggest that it was a deposit-feeder, possibly swimming to and from favorable feeding sites.
