FIGURE 6 in Morphological insights into the lobster genus Uncina Quenstedt, 1851 based on new material from the Ya Ha Tinda Konservat-Lagerstätte, Canada (Early Jurassic)
FIGURE 6. Box plots of morphometric measurements from Uncina species; the tops and bottoms of the colored boxes indicate the first and third quartile respectively and the solid black lines within represent medians. The whiskers outside of the boxes represent the lowest and highest datum (within 1.5 times the interquartile range), open circles outside of the whiskers indicate outliers; "n" refers to number of specimens (per species) with which that variable could be measured. A) Ratio of the propodus notch length to notch height in different species of Uncina. B) Ratio of the index length to index height in different species of Uncina. C) Total length of chelae in different species of Uncina. D) Ratio of manus length to index length in different species of Uncina. E) Ratio of the dactylus thickness to index height in different species of Uncina. F) Ratio of manus height at its minimum to manus height maximum for each uncinid species.

FIGURE 2 in Morphological insights into the lobster genus Uncina Quenstedt, 1851 based on new material from the Ya Ha Tinda Konservat-Lagerstätte, Canada (Early Jurassic)
FIGURE 2. Stratigraphic column of the East Tributary of Bighorn Creek section, Ya Ha Tinda Ranch, Alberta, Canada. Symbols denote the stratigraphic heights at which crustacean material was found as well as the elements and species (if applicable). Sepent. = Serpentinum, Falcif. = Falciferum, Eu = Europe, NA = North America. Lithostratigraphy and carbon isotope curve from Them et al. (2017) and fossil heights from Martindale et al. (2017). Some specimens are not reported from a particular horizon; instead, the collector Russell Hall (an ammonite biostratigrapher) noted the ammonite zone and so the age is assumed to be correct (dashed range). Specimens found in float from East Tributary can be assigned a minimum age; the river cuts up-section and so specimens not found in situ are interpreted to have originated from strata that are stratigraphically below the horizon in which they were found (dashed arrow).

FIGURE 1 in Morphological insights into the lobster genus Uncina Quenstedt, 1851 based on new material from the Ya Ha Tinda Konservat-Lagerstätte, Canada (Early Jurassic)
FIGURE 1. Paleogeographic map from the Early Jurassic indicating where Uncina lobsters have been found (Feldmann and Copeland, 1988; Karasawa, 2002; Schweigert et al., 2003; Martindale et al., 2017). The yellow star represents Ya Ha Tinda, Alberta, Canada, the red star represents the European sites bearing Uncina alpina and U. posidoniae, and the orange star represents the modern-day Japanese site bearing Uncina pacifica (Karasawa, 2002). Figure modified from Martindale et al. (2017).
