WALCOTT, Charles Doolittle [1850-1927] -- paleontologist, Mary Clark Thompson Medal
Mary Clark Thompson Medal (1921 1°, U.S. National Academy of Sciences)
Charles Doolittle Walcott
Working the Walcott-Rust quarry (Herkimer County, NY) he found
one layer (the "Ceraurus layer"), which yielded specimens uniquely preserved with calcified appendages, forming the basis of his earliest and still classic papers which first documented biramous limbs of trilobites.
In 1909 he discovered the fantastic Burgess Shale quarry, which he named in 1911.
Excavations here were to occupy him for the remainder of his life.
The degree of preservation of soft tissues in Burgess Shale fossils is remarkable.
