Juvenile specimens of the Paleocene–Eocene pantodont Coryphodon provide more extensive ontogenetic information for this genus than is available for other Paleocene–Eocene mammals. The dental eruption sequence for Coryphodon is: 1) (DC11, DI1–31–3); 2) DP44; 3) DP33; 4) DP22; 5) (M11, I33); 6) DP11, 7) M22; 8) P44; 9) P33; 10) (P22, I11?); 11) C11; 12) (M33, I22) (eruption sequence of tooth positions in parentheses is uncertain). The DP11 of Coryphodon do not have permanent successors. No significant, qualitative morphological variation can be detected in deciduous cheek teeth of Coryphodon, and metric analysis of these teeth failed to detect taxonomically significant differences. The ontogenetically youngest Coryphodon is known from parts of a skeleton of an individual perhaps less than three years old at the time of death. This skeleton and other partial juvenile skeletons suggest that juvenile Coryphodon grew quickly and approached near-adult proportions before the deciduous dentition was lost or the epiphyses of the long bones began to fuse.

To date, no unequivocal textual reference to the Great Sphinx has been identified prior to Egypt's New Kingdom. Here, we present evidence that the monument we now know as the Great Sphinx was called Mehit and that this name was part of an exclusive title held only by the highest officials of the royal Egyptian court going back to at least early dynastic times, i.e. prior to the time of the Great Sphinx's generally presumed construction during the 4 th Dynasty. Furthermore, the symbolic origins of this title precede the 4 th Dynasty by at least five centuries, going back to the very cradle of writing during the earliest dynastic era of the early Nile civilization. Based on this philological evidence corroborating geological and archeo-astronomical evidence previously published, we conclude that a lion-like stone monument existed on the Giza Plateau long before the Great Sphinx is generally believed to have been made and that early dynastic Egyptians referred to it in writing.

With the aid of energy‐dispersive X‐ray microanalysis, several protozoa were tested for content of cations within inorganic minerals. The skeleton of acantharia consists mainly of Sr with small quantities of Ca and Ba. Two Loxodes species contain nothing but Ba, while in some Remanella species Sr with small quantities of Ba were present. In one Geleia species, Ca with small quantities of Sr was found; in two Trachelocerca species from Sylt (Germany), Ba is there in addition. Another Trachelocerca species from northern Italy lacked Ba, but did possess Mn. In Prorodon only Ca was found.
