Van Valen (1978) provided the name Bomburia for an early Paleocene mammal (mioclaenid) from New Mexico. Christian F. Kammerer has kindly informed us that the name Bomburia Van Valen, 1978 (December), is the name of an extant hymenopteran, Bomburia Hedqvist, 1978 (July). We propose the new name Bomburodon (type species Ellipsodon priscus Matthew, 1937) as a replacement name for Bomburia. Bomburodon is named for Bombur, a fat dwarf in J. R. R. Tolkien's “The Hobbit” (1937) and “The Fellowship of the Ring” (1954–1955) and odon, tooth (Greek).

The specimen NHMUK 39514 comprises the cranial remains of a plesiosaur found on the Dorset coast during the middle of the ninetieth century. It was partially described and figured by Owen and variously attributed to Plesiosaurus rostratus (Owen) and to Plesiosaurus conybeari (Sollas). NHMUK 39514 is a partial braincase and mandible. It differs from all other Early Jurassic plesiosaurs known including the two species to which it was originally referred. The mandible presents several pliosauromorph characters but the specimen is identified as Plesiosauria indet. because it has several plesiomorphic characters in its braincase anatomy. This assignment will prevent the introduction of a possible chimera in future phylogenetical analyses and paleobiogeographic reconstructions.

A near complete shell from the Hemphillian 4 (Miocene/Pliocene boundary) Buis Ranch local fauna of Beaver County, Oklahoma, represents a fossil box turtle. An anterior contact of neural III and neural V with costal III and costal V only, respectively, presence of a small contact between the suprapygal and eleventh peripherals, development of a thin peripheral lip for articulation with the posterior plastral lobe, placement of the vertebral III/IV sulcus on neural VII, presence of two anterior musk duct glands, a rounded posterior plastral lobe, an elongate shell outline, and a complete neural series diagnose the fossil as a new species, Terrapene parornata n. sp. A phylogenetic analysis of fossil box turtles places T. parornata along the phylogenetic stem of the extant taxon T. ornata. The holotype of ‘Terrapene longinsulae’ cannot be distinguished from Terrapene ornata and is therefore synonymized. Finally, ‘Terrapene’ corneri lacks characters of crown group Terrapene and may therefore represent a stem box turtle. The provenance of the holotype of ‘Terrapene longinsulae’ is more poorly known than previously recognized and this specimen may originate from Kansas or Nebraska and be early Miocene to late Pleistocene in age. Terrapene parornata is therefore the oldest demonstrable representative of crown group Terrapene (ca. 5.3–4.6 Ma). ‘Terrapene’ corneri from the late Barstovian of Nebraska and fragmentary material from the middle Barstovian of Nebraska by contrast are the oldest representative of the Terrapene lineage (ca. 14.5–11.5 Ma). A review of morphological characters related to shell kinesis reveals that most are highly correlated. The results of the phylogenetic analysis converge upon those of molecular data when these correlated characters are omitted from the analysis.
