description: Dinosaurs
The dinosaur faunas of the Fruitland and Kirtland Formations were first described in detail by Gilmore (1916), who based his study on specimens collected by Bauer and Reeside. Subsequently, the collections of Charles Sternberg were described by Wiman(1930, 1931, 1932, 1933), Osborn (1923), Gilmore (1935) and Ostrom (1960, 1961). Kues et al. (1977), Lehman (1981), Rowe et al. (1981), Lucas et al. (1987) and others have described subsequent discoveries (Tables 5-7).

Crustacea
?Xanthoidea sp.
Bivalvia
Ostrea glabra
Anomia gryphorhynchus
A large, undescribed collection from the upper Fruitland has been amassed by Wolberg and co-workers in the Fossil Forest area. These specimens are dominated by disarticulated material but include partial skeletons (Hunt, 1984, 1991). They are housed at the University of Kansas and are being described by J. P. Hall.
Anomia gryphaeiformis
Modiola latiscostata
Unio holmesianus
Unio amarillensis
Unio gardneri
Unio reesiderei
The dinosaur specimens from the Fruitland and Kirtland Formations largely consist of disarticulated and isolated bones. Partial skeletons and skulls are uncommon (e.g., Wiman, 1930; Ostrom, 1961).
Unio brachypisthus
Unio neomexicanus
Unio brimhallensis
The dinosaur faunas of the Fruitland and Kirtland Formations were recently reviewed by Lucas et al. (1987). However, in the last 5 years there has been a marked increase in the literature on dinosaur taxonomy

with the publication of two important books (Weishampel et al .. 1990; Carpenter and Currie. 1990). Thus, we briefly review some aspects of the faunas and describe some recently collected specimens. Unfortunately, the recent literature lacks species-level revisions of some of the most important taxa, notably the Hadrosauridae, Ceratopsidae and Tyrannosauridae.
