[1] Mycomorphoolithus were first discovered (though not yet named) in 1990 by German paleontologist Rolph Köhring, who believed them to be the eggs of batagurine turtles.

[3] In 2015, the oogenus and oospecies Mycomorphoolithus kohringi was named by Moreno-Azanza et al. in honor of Köhring, based on the discovery of several fossil eggshell fragments in the Maestrazgo Basin of Spain.

Eggshell fragments discovered in England were described by Ensom in 2002, which are now referred to Mycomorphoolithus sp., were classified in the dinosauroid-spherulitic morphotype, and tentatively assigned to Faveoloolithidae (probably the eggs of sauropods[4]).

However, the 2015 description by Moreno-Azanza et al. shows that they are neither turtle nor dinosaur eggs, and suggests they were laid by a non-eusuchian crocodylomorph.

[1] Similar to krokolithids, and unlike dinosaur eggs, Mycomorphoolithus's eggshell units are isolated, have a blocky extinction pattern, and lack organic cores.
