Similifaveoloolithus is an oogenus of fossil dinosaur egg from the Tiantai basin in Zhejiang Province, China. It is the sole known oospecies of the oofamily Similifaveoloolithidae.[1][2]
Description
Similifaveoloolithus gongzhulingensis is known from nine specimens, including five complete fossil eggs; S. shuangtangensis is known from two complete fossil eggs. The eggs are spherical and the pores are very numerous and irregular, with a honeycomb-like appearance. They are 11-12 cm in diameter. The shell is composed of two or three superimposed layers of shell units. S. gongzhulingensis is distinguished from S. shuangtangensis by its thicker eggshell.[1][2]
Parataxonomy
Similifaveoloolithus is the only described oospecies of Similifaveoloolithidae. S. shuangtangensis was originally described as a species of Dendroolithus in 2003.[3] However, Wang et al (2011) considered it different enough from other ootaxa to be placed into a new oofamily and oogenus.[2] S. gongzhulingensis was originally described as a species of Dictyoolithus, but it was reclassified as a species of Similifaveoloolithus by Wang et al. (2013), because it shares much more in common with S. shuangtangensis than with the Dictyoolithids.[4][1]
