Cetiosauriscus (was RE: Sauropod name corrections)

[Tim Williams <tijawi@yahoo.com>]

_C. leedsi_ and _C. stewarti_ cannot be synonymous.  Here's the timeline, as I 
understand it:


(1) _Cetiosaurus leedsi_ (= _Cetiosauriscus leedsi_) was originally named  
_Ornithopsis leedsi_ by Hulke (1887).  Hulke based his species on fragmentary 
material (BMNH R1984â1988).


(2) Woodward (1905) assigned a second specimen (a partial skeleton, BMNH R3078) 
to _O. leedsi_.  In the same study, Woodward referred the species to 
_Cetiosaurus_, thereby creating the new combination _C. leedsi_.


(3) Huene (1927) referred _C. leedsi_ to a new genus, _Cetiosauriscus_.  This 
created the new combination _Cetiosauriscus leedsi_.


(4) Charig (1980) removed BMNH R3078 from _C. leedsi_ and assigned it to a new 
species, which he named _Cetiosauriscus stewarti_.  


(5) McIntosh (1990) referred _Cetiosaurus longus_ (named by Owen, 1841) to 
_Cetiosauriscus_, creating the new combination _Cetiosauriscus longus_.  


(6) Charig (1993) proposed that _C. stewarti_ be designated the type species 
for _Cetiosauriscus_.  His petition to the ICZN to have _C. stewarti_ replace 
_C. leedsi_ as the type species for _Cetiosauriscus_ (Case 2876) was approved 
in 1995 (Opinion 1801).  Thus, _C. stewarti_ is the official type species for 
_Cetiosauriscus_.


(7) In their review of the genus _Cetiosaurus_, Upchurch and Martin (2003) 
reject the referral of _C. leedsi_ and _C. longus_ to _Cetiosauriscus_, and 
regard both species as nomina dubia.  By contrast, _C. stewarti_ is regarded as 
a valid species, possibly a basal diplodocoid (Upchurch, 1995).
