This study describes a new member of Similifaveoloolithidae from the Upper
Cretaceous Zhoutian Formation of Jiangxi, China. The new ootaxon,
Wormoolithus luxiensis oogen. et oosp. nov., is erected based on eggs
collected from a partial clutch and represents the second oogenera of
Similifaveoloolithidae. Wormoolithus shares some unique features with
Similifaveoloolithus such as irregularly branched eggshell units, irregular
cavities in the inner part of eggshell that are worm-like in tangential
view and oblique pore canals in the outer part of the eggshell that show
honeycomb-like structure in tangential view. And it is distinguished from
the latter by longer polar axis and equatorial diameter and absence of
compact layer. Although the clutch is not complete, the preserved parts
show that the eggs are closely stacked in the nest. In addition, clay
minerals that occur in pores and a high estimated water vapour conductance
indicate a humid burial nest microenvironment.
