bones: three costals (ROM-42025, 42028 and 42029) and three peripheral bones (ROM-42026, 42030, and 2024).
Once a turtle was captured, we measured morphological variables and affixed radio transmitters (model R1850 [12 g] or model R1680 [3.6 grams], Advanced Telemetry Systems) to a single carapacial
scute using 5-min epoxy.
Any individual larger than the minimum observed size of adult males but not exhibiting the cloaca distal to the carapacial
rim was categorized as female, with females divided between mature and immature size classes based on the minimum sizes of females determined via palpation of eggs to be gravid (135 mm PL in G.
algae in a population of the Painted Turtle, Chrysemys picta.
We used the terminology and measurements suggested previously for cranial, postcranial, and carapacial
elements (Gillette and Ray, 1981).
To clarify the morphological specifications of turtle embryogenesis in late development, especially the formation of the carapacial
ridge (CR), researchers investigated into CR-specific miRNA expression, found existence of tissue-specific miRNAs and involvement of Wnt signaling.
That critical fold in the tissue maps out a line that becomes an important embryological feature of turtle embryos called the carapacial

carinae (Stahnke 1970): Am, anterior median; Cm, central median; Pm, posterior median; CL, central lateral.
caglei that were observed during the study were distinctive, with brightly colored, wide yellowish carapacial
UNSM 117938 from the Late Barstovian (ca 13-11.5 million EP) of UNSM Locality Cr 168, Cherry County, Nebraska, represents a single individual and consists of a mainly complete plastron, plus carapacial
