Similifaveoloolithus is an oogenus of fossil dinosaur egg from the Tiantai basin in Zhejiang Province, China.

[1][2] Similifaveoloolithus gongzhulingensis is known from nine specimens, including five complete fossil eggs; S. shuangtangensis is known from two complete fossil eggs of the Aptian Quantou Formation.

The eggs are spherical and the pores are very numerous and irregular, with a honeycomb-like appearance.

[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.
