CT scans of the best-preserved egg-clutch (CPPLIP 1798). (a) 3D rendering of the bottom of the clutch in CPPLIP 1798. (b) General view of the clutch at the same orientation, showing the external part of the lower hemisphere of the eggs. (c) Top view of the lower egg row, showing the inner part of the lower hemisphere of the eggs. (d) Lateral view of CPPLIP 1798, showing lower egg row with higher shells at both ends and part of the upper egg row. In dark orange, eggshell fragments within the eggs. Note that the incompleteness (“holes”) of some eggs in B and C are due to the lack of the eggshells and/or poor resolution of the CT scan. In A the shape of each egg is maintained due to the sedimentary internal mold. Scale bar 10 cm. (Dr Agustin G. Martinelli/Newsflash)
