| M. Moreno-Azanza et al. 2015 | Eggshells characterized by a single autapomorphy: Mushroom- shaped or inverted cone shell units comprising radiating wide crystals. They also differ from all previously known eggshell taxa in the following combination of characters: Eggshell with a mean eggshell thickness of 524 mm (n 1⁄4 96, SD 1⁄4 0.09, full range 0.31e0.81). Shell units are slender at the base of the unit, abruptly increasing in width up to fivefold at one third to one half of the eggshell. Pore openings vary in shape and dimensions, from 60 mm sub-circular pore openings to 300 mm oval to irregular pore openings that may be even larger due to the coalescence of adjacent pores. High pore density, ranging from four to 10 pores per square millimetre. Growth lines are straight to slightly wavy, over the entire eggshell thickness. |
