p. 374. Some things we know, some things we don’tlocked

  • Keith Thomson


‘Some things we know, some things we don't’ illustrates that palaeontology is a dynamic science because we still only know the fossil record imperfectly. The understanding that certain kinds of rocks were associated with particular fossils led to the first surface geology maps and with the stratigraphic column recognized as a unique time-sequence, the overall patterns in the fossil record became clear. The biggest gaps in the fossil record are right at the beginning in the Precambrian Aeon, the period between the earth forming some 4.5 billion years ago and the beginning of the Cambrian, 545 million years ago.
