Observations on dinosaur naming rate

• The overall trend is very obviously towards the more rapid naming of new dinosaur genera.

• There are large fluctuations between consecutive years.

• The last year with no new dinosaurs named was 1961; the previous was 1949. So we have had new dinosaurs every year but one of the last half-century.

• It took 158 years to name the first half of the genera; and 19 years to name the rest – eight times as fast!
