Using External Vertebral Growth Rings to Assess Longevity in the Bengal Monitor (Varanus bengalensis) (2003)

Gregory M. Erickson

An attempt was made to assess longevity using growth lines on bone surfaces from five, known-age, captive-raised Varanus bengalensis specimens. These monitors ranged in size from 22–52 cm SVL and...

Direct evidence of prey choice in carnivorous dinosaurs is rare in the fossil record. The most celebrated example pertains to purported stomach contents in the carnivorous dinosaur Coelophysis bauri,...

Growth patterns in brooding dinosaurs reveals the timing of sexual maturity in non-avian dinosaurs and genesis of the avian condition

Erickson, Gregory M, Curry Rogers, Kristina, Varricchio, David J, Norell, Mark A, Xu, Xing

The timing of sexual maturation in non-avian dinosaurs is not known. In extant squamates and crocodilians it occurs in conjunction with the initial slowing of growth rates as adult size is...

Brusatte, Stephen L., Carr, Thomas D., Erickson, Gregory M., Bever, Gabe S., Norell, Mark A.

Tyrannosaurid theropods are characterized by a generalized body plan, and all well-known taxa possess deep and robust skulls that are optimized for exerting powerful bite forces. The fragmentary Late...
