@smoran used an excellent strategy when we were working with a group of students last week. He has them all measure the largest tooth – Equus ferus – together, using the image from MacFadden, 1988 in the curriculum as a guide. This is an excellent formative assessment to ensure all students know how to measure the APL and crown height. It is one of the easiest teeth to measure, particularly when compared to Sifrhippus, and a great place to start before turning them all loose with the 15 species! Thanks, Sean!
