The Suffolk “Bone-Bed” or “ Coprolite-Bed.” 
The occurrence of a pebbly-bed, or a bed of nodules , in the Red 
Crag at Felixstowe, and generally in Suffolk where the base of the 
Red Crag or the Coralline Crag has been reached, has been described 
by Professor E. Ray Lankester, D.C.L., F. R.S. (Quart. Journ. Geol. 
Soc 1865, vol. xxi. pp. 221 — 232, Pis. x & xi, and ibid 1870, pp. 
493 — 514, Pis. xxxiii & xxxiv.). This bed which is from half 
a foot to three feet in thickness occurs at the base of the Crag and 
rests upon the London Clay. It is composed of rounded phosphatic 
nodules called “ coprolites,” and water worn teeth and bones of 
Mastodon arvernensis, Rhinoceros incisivus, R. Schleirmacheri,
