The study, published in the journal Nature, reveals for the first time how dinosaur embryos grew, developed and moved around within their eggs. The organic remains -- collagen discovered in bone -- also fuel hopes that many mysteries about dinosaurs may be resolved in the not-too-distant future.
“Our hope is that we may be able to recover collagen from these tissues in the future and do additional analyses,” project leader Robert Reisz told Discovery News. “This would take the study of early dinosaurs to another level.”
“Finding remnants of complex proteins in a 190-million-year-old fossil provides great promise for finding it in other extinct animals, if our targeted method is used,” added Reisz, a University of Mississauga paleontologist.
