Palaeobiogeographical significance of Early Silurian thelodonts from central Asia and southern Siberia
Early Silurian vertebrates, especially agnathans, from central Asia (Tuva and norhwestern Mongolia) and southerrn Siberia are abundant and diverse. The numerous microremains indicate that the strata of this region were deposited in warm, productive, shallow marine basins. The thelodont microremains...
