	Morphological Notes
	A11	The carbonate in layers 4 and 5 mainly occupies old faunal and floral passages. Layer 5 
	is in the middle of a very diffuse boundary of the B2 to C. Sandstone is present

	throughout the boundary zone between layers 4 and 5, but faunal activit
	A12	y has mixed clay with it. Sandstone per se occurs below 130cm, but is in the profile 
	from 100cm. So, to 130cm it may be transported, and below that may be in situ. 
	Carbonates stop at 145cm. The yellow sandstone from 130cm to end of sample i
	B21	s very soft, and has many white speckles of clay material (as in ed416). It may be that 
	the top 10cm is a recent sandy wash, though no sedimentary features are evident.
	Observation Notes
	Parent Rock: residual, sandstone, from sandstone, with lime Tertiary beds
	Site Notes
	Weak surface crust also evident. 100m below upper slope landform.
