For a sample, here's the current Ultrasaurus entry. The phylogenetic relationships will be considered further once I have a better framework to use.
|Ultrasaurus tabriensis holotype proximal humerus (DGBU-1973) in proximal (B) and anterior (C) views. Scale = 100 mm. After Lee et al., 1997.|
Ultrasaurus Kim, 1983
= "Ultrasaurus" Kim, 1981
U. tabriensis Kim, 1983
Aptian-Early Albian, Early Cretaceous
Gugyedong Formation, South Korea
Holotype- (DGBU-1973) proximal humerus (435 mm wide)
Paratype- ?(DGBU coll.) caudal neural spine
Referred- ? rib fragments (Kim, 1988)
? cervical vertebra (Kim, 1988)
Comments- Discovered in 1977, initially identified as a sauropod femur or tibia (Chang et al., 1982) or a proximal brachiosaurid ulna (Kim, 1981, 1983). Paul (1988) notes it is actually a proximal humerus. All modern authors have considered it an indeterminate sauropod, though as Barrett et al. (2002) note, the absence of a well-developed proximolateral humeral process excludes it from Somphospondyli at least.
