科：足杯虫科
属：足杯虫属
种：高足杯虫
描述:
高足杯虫的身体主要由上半部分的杯状萼与苞片和下半部分的柄与固着器组成。高足杯虫是一种珍稀的古海生动物，营底栖固着生活，其化石最早发现于加拿大，高足杯虫的萼的下方具有一个长柄，约44mm长，柄的底端具有一个灯泡状的固着器，以此来将自己固着在泥质海床的表面上。柄的上部为萼，是高足杯虫的采食器，其横断面为近椭圆形，内部有消化腔。萼的顶部有一圈苞片环，由18片苞片组成，排列在萼的周边。苞片呈棱角状，没有伸曲性，苞片的外侧光滑，内侧有褶皱和纤毛，苞片的长度约为8mm。苞片的作用大多被推测为是使水流在流过高足杯虫的顶部时在苞片环内产生涡流，涡流作用使得水中悬浮的食物颗粒与苞片内壁的纤毛有充分的接触机会，有利于提高采食的效率。

Order: Uncertain
Family: Dnimischidae
Genus: Dinomischus
Specie: isolatus
Description:
The body of the Dinomischus consists of a cup-shaped calyx and bracts in the upper part and a stalk and holdfast in the lower part. Under the calyx there is a long stalk, about 44 mm long, and the bottom part of the stalk has a bulb-like holdfast to fix itself on the surface of the muddy seabed. Above the stipe is the calyx, which is the feeding organ of the Dinomischus, with a subelliptical cross section and an internal digestive cavity. The top of the calyx has a bract circlet consisting of 18 bracts arranged around the perimeter of the calyx. The bracts are angular and not elongated, the outer side of the bracts is smooth, but the inner side has curves and cilia, and the length of the bracts is about 8 mm. the role of the bracts is mostly hypothesized to make the water flowing over the top of the Dinomischus produce vortex in the bract circlet, the vortex effect makes the food particles suspended in the water have sufficient contact with the cilia on the inner wall of the bracts, which improved the efficiency of feeding.
