Coarse tail grading

Webtail. The results from the Fusaru Sandstone suggest that inverse fine-tail grading is common in T a/S 3 divisions (Fig. 1a) and it indicates winnowing of fines during decreasing rates of suspended-load fallout. The inverse fine-tail grading tends to be associated with coarse-tail normal grading. Mud-rich sands WebNov 16, 2011 · The basal few metres show reverse coarse tail grading of both lithic and pumice clasts. The whole deposit is generally massive and is more pumice rich and lithic poor than the Diamante outcrop, including up to 20% pumice, with a maximum lithic clast size of 9 cm and average size <1 cm.

Webcoarse tail, large head, and wide muzzle relative to other cattle indicate that the calf is smaller framed and will have less genetic ability for gain. A long bodied, short tailed, fine haired calf weighing 500 lbs. should have more gain potential and ultimately have a higher yielding carcass with less trimmable waste.
