Cranidial and pygidial measurements, and cranidial landmark data of Sahtuia carcajouensis and Mackenzieaspis parallelispinosa ...
This dataset contains measurements and landmark data taken from two species of middle Cambrian trilobite from the Northwest Territories of Canada. This was conducted to quantify their growth and development. Following collection, specimens were prepared in the laboratory, coated in ammonium chloride...
