cognising this department of study as attractive and offering 

 scope for investigation I essayed the task. After laborious 

 journeys, meeting with non-success. I was rewarded with 

 some valuable finds in 1906. Some of these were entirely 

 new records for our district and were given by me to the 

 Middlesbrough Museum. Among the fossil plant- were : — 



1 . — Equisetites cohtmnaris. It consisted of the crushed 

 part of a stem, near the apex where the leaf sheaths 

 are close. 



2. — Otozamites graphicus. 



3. — Baiera Lindleyana. 



4. — Zamites species. This is a remarkably fine specimen 

 deposited in light brown sandstone (see illustration). 



With the valuable aid of Mr. Elgee, Assistant Curator of 

 the Dorman Memorial Museum, we determined three of these 

 plants correctly, but the plants were subsequently forwarded 

 to Mr. Seward, who confirmed our determinations. 



Zamites species has not been recorded previously from 

 the Bajocian in Yorkshire. It bears a striking resemblance 

 to a species named Z. Buchianus discovered among the 

 Wealden Flora, and suggests that the character of the vegeta- 

 tion of the world from the Upper Triassic period to the Wealden 

 to have been remarkably uniform and constant in its main 

 features. 



Otozamites graphicus, and Baiera '„ Lindleyana are new 

 records for the North- West Cleveland area. 



The geological horizon from which these plants were de- 

 rived is the Inferior Oolite of Estuarine origin. This sand- 

 stone bed in the neighbourhood of Carlton Bank is full of 

 plant remains, and some short time age a fossilised tree a 

 few yards in length was seen and awakened much interest. 

 This sandstone attains a greater thickness in this locality 

 and contains less shale than further east and was probably 

 deposited in the estuary of a river flow ing from west to east 

 in early Oolitic times.
