Holotype- (UM 84) tooth
Comments- Huene (1923) stated that if the dorsal vertebrae (BMNH R1828; later made the holotype of Becklespinax altispinax) were shown to belong to Megalosaurus dunkeri, it would be renamed Altispinax. Kuhn (1939) was the first author to definitively tie a species to the genus, making Altispinax dunkeri official. The conditional nature of Huene's (1923) statement prevents it from attaching the name Altispinax to the vertebrae by ICZN rules (contra Rauhut, 2000).

Altispinax? "lydekkerhueneorum" Pickering, 1984 vide Pickering, 1995

Hastings Beds, England
Material- ?(BMNH 604a-d)
?(BMNH 2559)
(BMNH R1828) caudal vertebrae
? about 30 other specimens
Comments- BMNH R1828 is intended to be the holotype. It was originally referred to Altispinax by Huene (1923), though there is no overlap with the holotype tooth of the latter taxon, so this assignment is doubtful. There is no publically available diagnosis, and it is uncertain whether this specimen is indeterminate or whether the referral of additional specimens can be supported.

= Creosaurus potens Lull, 1911
= Dryptosaurus potens (Lull, 1911) Gilmore, 1920
Aptian, Early Cretaceous
Arundel Formation, Maryland, US
Holotype- (USNM 3049) (7-10 m) proximal caudal centrum (140 mm)
Diagnosis- proximal caudal centra slightly opisthocoelous; proximal caudal centra with single ventral keel.
Description- The holotype was collected by J. K. Murphy in a Washington D.C. sewer. Comparison with Allosaurus (Madsen, 1976) indicates that the holotype is probably from the fifth or sixth caudal vertebra. Based on this, it is probably from an animal 7-10 meters long. Although Gilmore (1920) referred the mid-portion of a large pedal ungual I (USNM 8505) to this taxon, this was only based on size and provenence. No valid criterion suggest such an assignment was warrented, so it will not be discussed further.
The specimen is a proximal caudal centrum missing the neural arch and spine. In addition, some of the posterior surface has been abraded. The centrum is slightly opisthocoelous, with the anterior articular surface slanted slightly posteroventrally. It is strongly compressed laterally (anterior face 130 percent as tall as wide) and roughly oval in anterior view, with flattened sides. The neural canal is broad, though constricted in the middle. Ventrally, the centrum shows a single median keel, with a chevron facet posteriorly. Additionally, the ventral edge is only very slightly concave in lateral view. It is cancellous internally and lacks pleurocoels.
Relationships- Comparison to other theropods is difficult due to both the fragmentary nature of the specimen and the few detailed descriptions of caudal centra in the literature. As "Capitalsaurus" was discovered in Cretaceous deposits, it is assumed that the centrum did not derive from a basal theropod such as a coelophysoid or Dilophosaurus, which are only known from the Triassic and Early Jurassic. This species has been referred to Allosaurus and Dryptosaurus in the past, but is stratigraphically closest to Acrocanthosaurus. It will be compared to these three genera first, then to other genera that may be similar. The proximal caudals of Allosaurus are amphiplatyan to slightly procoelous, the opposite of "Capitalsaurus". Also, they are about as wide as tall, sometimes wider, and the ventral edge is much more concave. The ventral surface has a slight groove instead of a keel. Those of Dryptosaurus share the straighter ventral edge and are slightly taller than wide (~1.05 times), but no further details can be discerned. Acrocanthosaurus has caudal pleurocoels (like Carcharodontosaurus, but not Giganotosaurus), a concave ventral margin and amphiplatyan or amphicoelous centra. The ventral surface is grooved and the centra are 1-1.2 times taller than wide. The only theropod described as having opisthocoelous caudals is the segnosaur Nothronychus. This taxon differs from "Capitalsaurus" in having a median ventral groove, pleurocoels, an autapmorphic posterolateral tubercle, larger chevron facets and being slightly wider (1.16 times taller than wide). Among other segnosaurs, at least Neimongosaurus and Segnosaurus lack opisthocoelous centra. Several theropods are known to lack ventral grooves on the proximal caudals. These include Elaphrosaurus, Carnotaurus, Eustreptospondylus, Suchomimus, Sinraptor dongi, "Alashansaurus", Ornithomimus? sedens and alvarezsaurids. Of these, only alvarezsaurids are known have ventral keels, though the condition in most others is uncertain in this regard. Although most other theropods (eg. Ceratosaurus, Torvosaurus, Monolophosaurus, Nedcolbertia, Sinraptor hepingensis, Tyrannosaurus, Archaeornithomimus, Gallimimus, Microvenator, Chirostenotes) are described as having a ventral groove, the condition in Sinraptor dongi at least changes from convex in the proximal caudals to grooved in the mid and posterior caudals. This suggests our knowledge of which theropods have convex ventral surfaces on their proximal caudals is extremely limited, and subject to change as specimens are described more fully. Although alvarezsaurids do have ventral keels, they are otherwise quite dissimilar to "Capitalsaurus" in having strongly procoelous centra. Several theropods are similar to "Capitalsaurus" in having centra over 1.2 times taller than they are wide, including Monolophosaurus, sinraptorids and Bagaraatan. Theropods known to have more circular centra are Ceratosaurus, Carnotaurus, Elaphrosaurus, Torvosaurus, Baryonyx, Piatnitzkyosaurus, Allosaurus, Acrocanthosaurus, Carcharodontosaurus, Dryptosaurus, ornithomimids and oviraptorosaurs (which are diagnosed in part by their wide caudal centra). Paravians have distinctively subrectangular centra, so "Capitalsaurus" can be excluded from this clade. The condition found in "Capitalsaurus", where the ventral edge of the centrum is nearly straight, is extremely rare in theropods, being otherwise noted in Dryptosaurus, tyrannosaurids and Bagaraatan. This can vary greatly with position in some taxa such as Bagaraatan, so undue emphasis shouldn't be placed on the character. While clearly not a derived oviraptorosaur or paravian, the current phylogenetic utility of proximal caudal centra does not allow placement more precise than assumed Neotheropoda incertae sedis. While currently unique compared to described theropod caudals, the amount of variation between caudal centra in single specimens is just starting to be revealed (Sinraptor dongi's ventral groove/keel; titanosaurid's articular surfaces varying from opisthocoelous to procoelous; Bagaraatan's ventral edge concavity). Because of this potentially high variation, I am extremely cautious as to the taxonomic utility of this caudal centrum and only doubtfully retain it as a valid taxon.
Comments- The genus "Capitalsaurus" was only used in a faunal list by Kranz (1998), though Kranz (pers. comm.) informs me it is meant as a replacement name for Creosaurus potens. As it has not been associated with a particular species or specimen in the literature, it is a nomen nudum.

Chienkosaurus Young, 1942
C. ceratosauroides Young, 1942
Tithonian, Late Jurassic
Shangshaximiao Formation, Sichuan, China
Holotype- (IVPP V237) premaxillary tooth (73 mm)
Paratypes- ?(IVPP V190) partial mid caudal centrum
?(IVPP V193) ulna (225 mm)
Comments- Three other teeth included in the holotype are from Hsisosuchus (Dong et al., 1983).
The tooth is similar to many large theropod teeth in general characters, but is from the premaxilla as evidenced by the twisted anterior carina and reduced extent of anterior serrations. It is currently undiagnostic compared to contemporaneous taxa like Sinraptor and Yangchuanosaurus.
The referred ulna is most similar to Piatnitzkysaurus, though no ulnae are currently known for sinraptorids. It differs from Piatnitzkysaurus in not being bowed posteriorly, and the olecranon appears broken off. This is a more diagnostic specimen than the holotype, but is unfortunately not definitely referrable to the same individual or taxon.
The referred caudal centrum is from a different locality, so is definitely not referrable to the holotype individual, but was thought to be “probably referrable” to Chienkosaurus by Young. Comparison to Allosaurus suggests it is from somewhere around caudal twenty-five, but it is indeterminate.

"Prodeinodon" kwangshiensis Hou, Yeh and Zhao, 1975
Aptian-Albian, Early Cretaceous
Napai Formation, Guangxi, China
Holotype- four teeth
Comments- This species reportedly resembles Wakinosaurus more than Prodeinodon (Okazaki, 1992), though the morphology of either genus has not been compared to most other theropods. Thus, the resemblence may not mean much.

"Scrotum" Brookes, 1763
"S. humanum" Brookes, 1763
Late Bajocian-Bathonian, Middle Jurassic
oolitic limestones of Cornwell, England
Material- (lost) distal femur
Comments- Originally described and illustrated by Plot (1677). Brookes (1793) later applied the name "Scrotum humanum" to the specimen, although probably not intending it as a Linnaean binomial. With the nomen oblitum clause of the ICZN no longer active, Halstead petitioned the ICZN to suppress the name in favor of Megalosaurus bucklandii. However, the ICZN felt that such action was uncessary since it is not necessarily a M. bucklandii specimen. Indeed, though often associated with Megalosaurus, there is no reason it couldn't be a contemporaneous form like Metriacanthosaurus or the unnamed Stonesfield abelisaurian instead.

Streptospondylus? cuvieri Owen, 1842
= Megalosaurus cuvieri (Owen, 1842) Huene, 1907-1908
Early Bathonian, Middle Jurassic
Chipping Norton Formation, England
Holotype- (lost) anterior portion of dorsal vertebra
Comments- Eustreptospondylus oxoniensis was referred to Streptospondylus cuvieri before it was named. This taxon is not necessary the same as Streptospondylus altdorfensis, which lived later in France.

Szechuanosaurus Young, 1942
S. campi Young, 1942
Tithonian, Late Jurassic
Kyangyan (Guangyuan) Series, Sichuan, China
Cotypes- (IVPP V235) two partial teeth
(IVPP V236) partial tooth
(IVPP V238) fragmentary teeth
(IVPP V239) tooth
Referred- ?(UCMP 32102) tooth (90 mm), ischial fragment, femoral fragment (Camp, 1935)
? three cervical vertebrae, two anterior dorsal vertebrae, proximal caudal vertebra, coracoid, ischium, tibia, fibula, metatarsal (He, 1984)
Diagnosis- Provisionally indeterminate relative to at least Sinraptoridae.
Comments- The partial skeleton often referred to this species has been referred to "Szechuanoraptor" zigongensis by Chure (2000). The cotype teeth were collected from a wide area and may not belong to one taxon. Camp's (1935) specimen is from the Cretaceous Szechuan Beds of Sichuan, China. Young (1942) referred it to S. campi, but there is no reason for this assignment. He's (1984) specimen was found to be an indeterminate basal tetanurine by Chure (2000), and cannot be compared to Szechuanosaurus.
