Figure 15.

Transverse mid‐branch section of Hornera cf. robusta, frontal side up. On the abfrontal side the lateral autozooid chambers (L) are empty, except for residual brown bodies (B) and sparse endocystal cell cover. Away from branch tips, polypides of lateral autozooids are located only at the lateral edges of the branch in wide‐branched hornerid taxa. Note significant dimorphism of frontal and lateral autozooid diameter in this species. C, cancellus; P, pharynx; T, tentacle. Scale bar in µm
