Antodendrina igen. nov.

urn:lsid:zoobank.org:act: F13A16FD-226A-4AFB-852A-3A53A2C3E2FF

Type ichnospecies

Antodendrina ligula igen. et isp. nov.

Diagnosis

Closely prostrate bioerosion trace in calcareous skeletal substrates, with radiating and distally widening lobes emerging from a central cavity, the latter and the lobes being in direct lateral contact to the substrate surface or forming open depressions.

Etymology

Latinised from the ancient Greek ‘ἄνΘος’ (antos), blossom, and ‘δένδρον’ (dendron), tree, referring to the blossom-like radial appearance of this dendrinid’s outline.

Remarks

The diagnostic morphological feature of a central depression with radiating club- to spoon-shaped lobes is unique among the Dendrinidae and is the primary ichnotaxobase of this new ichnogenus. Unlike Dendrina, the radiating lobes are in direct contact with the substrate surface.
