Description
Subtriangular and rounded dark organic remains of apparently homogeneous texture; 0.5 to 1.5 mm. long, 0.2 to 0.4 mm. wide; longitudinal section showing long, thin, straight and parallel canals distributed in regular but intermittent pattern; transverse section showing minute pores either arranged in 2 or more flattened, oblong rings or distributed irregularly; diameter of pores 12 to 40 microns. [Interpreted by PAREJAS (1948) as coprolites of crustaceans, by CUVILUER (in CUVILLIER &; SACAL, 1951) as primitive Charophyta, by BRONNIMANN (1955) as microfossils ineertae sedis, and by BRONNIMANN &; NORTON (1960) as coprolites of crustaceans (Anomura). KENNEDY, JAKOBSON, &; JOHNSON (1969) described an association of Thalassinoides with the microcoprolite Favreina from the Great Oolite Series of England.]
