FIGURE 3 in Taxonomic Identification Of The Megaloolithid Egg And Eggshells From The Cretaceous Bauru Basin (Minas Gerais, Brazil): Comparison With The Auca Mahuevo (Argentina) Titanosaurid Eggs
FIGURE 3: Eggs and eggshells from the locality of Peirópolis, Marília Formation, Bauru Basin (from Magalhães Ribeiro, 2002). A: Note the elongated sub‑spherical shape of this titanosaurid egg. The presence of a single egg with eroded eggshell fragments combined with grain size of the silicoclastic sediments suggests that the egg was transported and the Peirópolis locality, in contrast to Auca Mahuevo (Patagonia), is not the primary nesting site of these dinosaurs. B: Similarly to the well‑identified titanosaurid eggs from Auca Mahuevo, the eggshell surficial ornamentation of the Peirópolis material displays single and coalescent nodes. C: Eggshell accumulation and compaction on a single slab suggesting that the egg was subjected to taphonomic forces as it was still unbroken, a process also observed in Auca Mahuevo. D: SEM view of the radial section of a Peirópolis eggshell that displays the same eggshell structure with radiating acicular crystals and shell units arrangements as those from Auca Mahuevo. E: TLM view of a Peirópolis eggshell that shows organic lines that cross horizontally the eggshell thickness as observed in specimens from Auca Mahuevo.
FIGURE 2 in Taxonomic Identification Of The Megaloolithid Egg And Eggshells From The Cretaceous Bauru Basin (Minas Gerais, Brazil): Comparison With The Auca Mahuevo (Argentina) Titanosaurid Eggs
FIGURE 2: Eggs and eggshells from the locality of Auca Mahuevo, Rio Colorado Formation, Neuquén Basin. A: Titanosaurid egg found on the surface of stratigraphic egg layer 3. Note the sub‑spherical shape of the specimen here considered either as a biological character of this saurischian family or influenced by taphonomic processes coupled with a certain eggshell plasticity due to its mono‑layered structure. B: The site of Auca Mahuevo is interpreted as a flood plain with seasonally over banking rivers where titanosaurid dinosaurs would exhibit colonial nesting and site fidelity behaviors. A large number of egg clutches are surfacing in several stratigraphic egg layers. C: Eggshell surficial ornamentation displays single and coalescent nodes (two black arrows where nodes coalesce). D: SEM image of the perfect nodular ornamentation of titanosaurid eggshells with round pore apertures located in the interstices between the nodes. E: SEM detail of figure 1D. F: cross section of a titanosaurid eggshell that shows a pore canal (arrow 1) transecting the entire thickness of the mono‑layered eggshell. Note the network of connecting vertical pores with a system of horizontal pore canals here only visible because of the MT preservation. G: TLM view of a thin section that contains two eggshell fragments facing each other. Note the cores of the shell units as shown by arrow 1, the shell units (arrows 2 and 3) crossed by lines that are interpreted as ex‑organic structures, and the MT (arrow 4) preserved only in one section of the slab.
