Oodnadattia
From Fensome et al., 2019:
"Oodnadattia", Eisenack and Cookson, 1960, p.6.
Taxonomic senior synonym: Dinopterygium, according to Norris and Sarjeant (1965, p.44) and Lentin and Williams (1985, p.259).
Taxonomic junior synonym: Xiphophoridium, according to Below (1981a, p.64) -- however, Lentin and Williams (1981, p.294) retained Xiphophoridium.
Type: Eisenack and Cookson, 1960, pl.2, fig.10, as Oodnadattia tuberculata.

Original description: [Eisenack and Cookson, 1960]:
Description:
Shell broader than long, apical and antapical surface convex, circular to broadly oval in outline with an embayment made by longitudinal furrow. Transverse furrow circular, narrow, bordered by two broad membraneous wings; longitudinal furrow winged especially in the hypotheca. The plates of the epitheca and hypotheca are bordered by low ledges and separated by radially arranged retangular intermediate plates.
Affinities:
The genus Oodnadattia is distinct from Dinoryterigum Deflandre 1935 in the absence of high ledges and the presence of intermediate plates in both epitheca and hypotheca.
