Ha encontrado fósiles con vasos sanguíneos extraordinariamente bien conservados y tejidos blandos, pero nunca ADN intacto. Por eso, en un nuevo enfoque, está tomando descendientes vivos de los dinosaurios (los pollos) y modificándolos genéticamente para reactivar rasgos ancestrales -incluyendo dientes, colas, e incluso manos- para hacer un “Pollosaurus".
