Description

Ciuciulea is a dwarf cetotheriid 3-4 meters in length. It differs from the other Cetotheriidae in the presence of a narrow occipital shield, which is as long as wide, and a pars cochlearis of the periotic bone bulging out ventral to fenestra rotunda. Primitive characters include the premaxillae forming a transverse line with the posterior ends of nasals and maxillae rather than constricted or overridden by ascending processes of maxillae.[1]

Biology

Ciuciulea lived in shallow marine waters in present-day Moldova, earlier than true seals Pontophoca, Sarmatonectes, Histriophoca, Monachopsis, Cryptophoca, and Praepusa, the putative kentriodontid Sarmatodelphis, and the problematic odontocetes Pachypleurus, Phocaena euxinica, and Delphinus bessarabicus.

gollark: They vary too much by locale anyway, so I don't think I could answer for you without extra research.
gollark: I didn't check because it didn't seem particularly worth learning about boring things like zoning laws.
gollark: I did wonder about this. It seems like the ideal, optimal, entirely flawless way to live would be to attain a giant warehouse of some kind and stick computers and a bed in one corner.
gollark: Some online friends did vaguely express interest in running our IRC network over ham radio instead of boring IP networks. That might be neat.
gollark: It's on my list of things to eternally never get round to doing.
