Paradictyoolithus

Paradictyoolithus is an oogenus of dictyoolithid dinosaur egg from the Zhejiang Province, China.

[1] Both Paradictyoolithus oospecies are from the Chichengshan Formation in Tiantai County, Zhejiang, China.

[1] This formation was determined to be 91 to 94 million years old (early Upper Cretaceous) by Uranium–lead dating.

However, in 2013 the Chinese paleontologists Wang Qiang, Zhao Zi-Kui, Wang Xiao-Lin, Zhang Shu-Kang from the Chinese Academy of Sciences working together with Jiang Yan-Gen from the Tiantai Bureau of Land and Resources of Zhejiang Province, described several new dictyoolithid specimens, including both oospecies of Paradictyoolithus.

[1] Paradictyoolithus eggs are roughly spherical, measuring 10.8–13.9 cm (4.3–5.5 in) in diameter.
