Figured specimen. — Negative 5899; Trivoli 

 Cyclothem, maceration 1175-P, slide 7, co- 

 ordinates, 131.6 X 49.0; size, 28.2 by 24.7 ft. 

 This species also was found in macerations 

 1175-A through 1175-D. 



Granulatisporites sp. 3 

 Plate 2, figure 18 



The spore is radial, trilete, triangular in 

 outline, and has broad corners and concave 

 interradial sides. The rays are distinct and 

 at least three-fourths the length of the spore 

 radius. Lips are poorly developed. The sur- 

 face of the spore coat is ornamented with 

 widely scattered papillate projections, 4 to 

 5.5 fi long and up to 3 ft wide. Small scat- 

 tered grana also are present. The exine is 

 about 2 ft thick. 



Figured specimens. — Negative 5535; Hen- 

 shaw Formation, maceration 1122-Q, slide 

 11, coordinates, 133.4 X 55.6; size of largest 

 specimen, 32.4 by 29.2 ft. 



Granulatisporites sp. 4 

 Plate 2, figure 19 



These spores are very similar to that de- 

 scribed and illustrated by Butterworth and 

 Williams (1958, p. 365, pi. 1, fig. 41) as 

 Pustulatis pontes papillosus (Knox) Potonie 

 & Kremp, 1955. Knox (1950, p. 327) de- 

 scribed P. papillosus as having concave sides 

 and being ornamented with tuberculate proc- 

 esses 2 fx long. Butterworth and Williams 

 gave the length of the tubercles on their speci- 

 mens as up to 8.5 ft long, with variable orna- 

 mentation even on the same specimen. 



Figured specimen. — Negative 6112; Trivoli 

 Cyclothem, maceration 1175-B, slide 5, co- 

 ordinates, 138.1 X 37.8; size, 41.2 by 35.7 ft. 

 This species also was found in maceration 

 1175-D. 



Granulatisporites sp. 5 

 Plate 2, figure 20 



The spore is radial, trilete, and roundly 

 triangular in outline, and has broad, well 

 rounded corners. The rays are distinct, 

 straight, and about two-thirds the spore ra- 

 dius. Area contagionis is slightly thicker than 

 the rest of the spore coat. The spore coat, 

 about 2.5 ft thick, is seen to be levigate under 

 oil immersion objective. 



Figured specimen. — Negative 4749; Trivoli 

 Cyclothem, maceration 1128-1, slide 16, co- 

 ordinates, 130.3 X 52.2; size, 42.2 by 41.2 ft. 



Granulatisporites sp. 6 

 Plate 2, figure 21 



The spores are radial, trilete, triangular in 

 outline, and have well rounded corners and 

 convex interradial sides. The distinct, straight 

 rays extend almost to the margin. The prox- 

 imal and distal surfaces are covered with 

 cone-shaped verrucose projections and flat 

 spines about 3 ft long. The exine is about 



2 ft thick. 



Figured specimen. — Negative 5552; Hen- 

 shaw Formation, maceration 1122-A, slide 



3 ZB, coordinates, 141.9 X 46.6; size, 38.6 

 by 37.0 ft. This species also was found in 

 maceration 1122-CC. 



Granulatisporites sp. 7 

 Plate 2, figure 22 



The spore is radial, trilete, and triangular 

 in outline, and has well rounded corners and 

 straight to convex interradial sides. The rays 

 are distinct, straight, and about two-thirds 

 the length of the spore radius. The proximal 

 and distal surfaces are covered with grana 

 that are broader than high and vary in size 

 from less than 1 ft to 3 ft in diameter. They 

 are largest at the corners, where they project 

 beyond the margin. The spore coat is about 

 1 ft thick.
