*Holotype--OMNH 03030 (formerly OUSM 1-0-S83; listed by Fielitz and Bardack, 1992:133 and fig. 1, as OMNH 1-0-283); nearly complete, three-dimensionally preserved body; Fielitz and Bardack (1992, figs. 1-8).
Locality and Age--V463, Britton, Texas; Eagle Ford Formation; Late Cretaceous.
Comments--At the time this specimen was nominated, no locality data were known to be available, but based on its unusual preservation, Fielitz and Bardack (1992) determined that the horizon and locality of origin of the specimen were "Probably Eagle Ford Shale (Upper Cretaceous), and possibly from rocks of this formation in vicinity of Fort Worth or Dallas, Texas. . . . The specimen has been in the Oklahoma collection for at least 50 years." While their paper was in press and during the renovation of our vertebrate paleontology collection in 1991, one of us (NJC) located a few undated photographs of this specimen, originally made by Donald E. Savage, labeled simply "q Tex.-1-J" and "Teleost from Britton, Texas." Thus its occurrence in the Eagle Ford Shale near Dallas and Fort Worth, as inferred by Fielitz and Bardack, has been confirmed, and a type locality is established hereby.

Brontotheriidae
Menodus bakeri Stovall, 1948a:89
Holotype--No holotype was designated. In the original description, Stovall listed "a lower jaw, which lacked only the incisors of being complete, about 12 vertebrae, several damaged ribs, an almost complete femur, and a few foot and toe bones." No indication is given as to whether this collection of skeletal parts was actually associated. The mandible lacking incisors (MUO 18-4-S17; now OMNH 16561) was illustrated (Stovall, 1948a, pl. 1, fig. 7) with a caption reading "Mandible of Menodus bakeri sp. nov." and can be considered to be the holotype.
Locality and Age--Among the Presidio County, Texas, materials collected by Stovall, two localities apparently are involved, although only one is mentioned in Stovall (1948a). The two localities are: V459; field loc. 40-III-1 (on paper field labels and inked directly onto some specimens). This should be the locality shown on Stovall's (1948a) map. According to Wilson (Wilson et al., 1968; Wilson, 1971, 1974), the site is incorrectly plotted on Stovall's map. In addition, a small scrap of paper that was placed with the tapir specimens (Colodon stovalli Wilson and Schiebout) from this locality and handwritten by Wilson states that one of Stovall's figured specimens (1948a, identified as Protapirus sp.) fits on Texas Memorial Museum 40206-37. As the paper states, "this proves that the OU party collected near Big Cliff and not near tunnel road as shown by Stovall. J. A. W., Oct. 1980." The site is in the Chambers Tuff Formation of the Vieja Group. V460; field loc. 40-III-2. This locality is not mentioned or shown on Stovall's (1948a) map. A note in Stovall's handwriting, found with some of the Trans-Pecos specimens, mentions "B. B. [Big Bend] . . . 40-III-2 Van Horn Texas." The town of Van Horn is in Culberson County, Texas, several miles to the north of 40-III-1. The site presumably is in the Vieja Group. It cannot be determined from Stovall's description of Menodus bakeri whether specimens of this new species came from one or both localities. The note with specimens 40-III-2 reads "misc. ribs and vert. frags many of which fit other pieces." Only one of the many Trans-Pecos specimens, a nearly complete femur, is actually inked 40-III-2, although a few vertebrae are inked with "III-1-2-40." Thus, it is unclear whether these materials represent one individual or several. A few redundant elements (2 axis vertebrae, 3 left unciforms) occur among the materials, but, because most are not labeled with 40-III-1 or 40-III-2, it is not possible to clarify the situation by referring to field numbers.
Comments--The mandible actually lacks more than its incisors. As can be seen in the illustration (Stovall, 1948a, pl. 1, fig. 7), all the premolars also are missing. However, the right p2 and p3 shown in Stovall (1948a, pl. 1, fig. 9), as well as one-half of the right p4 (not illustrated) have been fitted with plaster onto this mandible since the illustrations were made. Although these premolars are less worn than the molars, there seems to be an original fracture-contact between the base of the posterior root of the p3 and its root remnant within the mandible. The premolars have the following old catalog numbers and field number written on them: p2, 19-26-S69 (not 19-2-S8 as is indicated in the caption to pl. 1, fig. 9); p3, 19-26-S68; p4, 40-III-1 and 19-26-S67. Since Stovall's (1948a) drawing was made, the canine has been lost from the mandible.


M. [sic] bendi Stovall, 1948a:91
*Holotype?--OMNH 02991 (MUO 19-2-S8), associated maxilla and left series of mandibular teeth; Stovall (1948a, pl. 1, figs. 8, 9).
Locality and Age--V459?, Presidio County, Texas; Chambers Tuff Formation(?); Oligocene (Chadronian).
Comments--In the same paper as that mentioned under Menodus bakeri, Stovall (1948a:91 and pl. 1, figs. 8 and 9) discussed a second kind of titanothere that he apparently intended to name as a new genus and species. He illustrated two pieces (both given the number MUO 19-2-S8), presumed to have been associated. The specimen consists of a maxillary fragment with broken P4-M2 (fig. 8; now OMNH 02991) and associated "almost complete series of teeth from the lower left side of the mandible" (p2-3 shown in fig. 9). In the caption for pl. 1, fig. 9, he provided the abbreviated name "M. bendi gen. et sp. nov." Measurements for the specimen were provided in the figure captions. No nearly complete series of left mandibular teeth was found during our collection renovation of 1988-93. The p2-p3 shown in pl. 1, fig. 9 have been repaired onto the Menodus bakeri mandible (see above) and were not numbered 19-2-S8. In the text, Stovall (1948a:91) discussed the specimen as "An unidentified titanothere" without providing the spelling of the intended generic name, designating a holotype specimen (except that only one, which was illustrated and numbered, was involved), or noting which of the localities it originated from (see
Locality and Age notes for Menodus bakeri, above). In subsequent paragraphs, however, he provided what might be considered the generic and specific diagnosis, differentiating it from Menodus.
