erosion took place, in producing the material for these sedimentary 

 beds. It is, however, difficult to explain why the eroded bones should 

 lind a place in these quietly deposited sediments, while the rock 

 products of the same erosion are not present either as conglomerates 

 or as isolated pebbles or boulders". Anderson saw no sign of plant 

 remains; he pointed out that the ferruginous material segregated 

 around the bones which varied in size from an inch to three feet 

 in length. He considered that the bone-bearing nodules were con- 

 fined to more or less distinct horizons on which the individuals are 

 fairly plentiful. Large hones and small bones are mixed together 

 indiscriminately the two chief horizons being one amongst the 



lower shales and the other some distance higher. 



Dr. Broom, who examined these remains, could not be certain of 

 their specific identity. He considered it not improbable that they 

 were all representative of one species, pointing out their resemblance 

 to Gresslij< sawus and their possible identity with Euskelesaunis brou'ni 

 or Euskelesaurus capensis. 



Neither Mellor nor Kynaston recorded determinate fossils, but 

 in a bore hole at Lndluw "2355 specimens of Cyzicus (= Esther i-a) (?) 

 were found in sandstone. Van Hoepen has described also a new genus 

 of Theropod - - Giyantoscelus - - from bones in the Transvaal Museum 

 which came from Haakdoornbult 314 in the district of \Yaterberg to 

 the west of Pienaars River Station. 



Kottiati Poort Area. The Hush veld Sandstone of the Komati Poort 

 coalfield was described by Kynaston in 1900. In that area, fine-grained 

 sandstones with distinctive features lie between the Coal Measures 

 and the amygdaloidal basalts. 



The sandstones are usually without signs of stratification. They 

 are very fine-grained, even-textured throughout, soft, pale greyish or 

 yellowish, sometimes pinkish in colour, sometimes mottled with darker 

 spots. At one outcrop numerous spherical concretions up to 9 in. 

 in diameter were seen, consisting of a hard shell around a softer 

 interior. 



Towards the base, the series becomes calcareous, and is often crowded 

 with irregular lumps or nodules of finely crystalline limestone. Below 

 this occur thin-bedded, soft, dark-red and greenish sandy shales and 

 marls, the red colour predominating. The total thickness of the 

 series is 300 feet. No organic remains have yet been discovered in 

 the beds.
