Científicos han identificado restos de colágeno original en un fósil de Edmontosaurus de Dakota del Sur. El hallazgo, publicado en 2025, desafía la creencia de que todo el material biológico se pierde durante la fosilización.

Investigadores de la Universidad de Liverpool examinaron un hueso sacro de 22 kilogramos de un fósil de Edmontosaurus recuperado en la Formación Hell Creek. Mediante espectrometría de masas, secuenciación de proteínas y otras técnicas de laboratorio, detectaron restos de colágeno, la principal proteína del tejido óseo. Colegas de la UCLA confirmaron la presencia de hidroxiprolina, un aminoácido vinculado al colágeno, lo que refuerza la tesis de que las moléculas provienen del propio dinosaurio y no de una contaminación moderna.

Researchers at MIT have discovered chemical evidence in rocks over 541 million years old suggesting that ancient sea sponges were among Earth's first animals. The findings, published in the Proceedings of the National Academy of Sciences, identify molecular fingerprints matching compounds from modern demosponges. This builds on earlier work and confirms the signals originate from biological sources rather than geological processes.

Researchers have named a newly identified juvenile dinosaur species Doolysaurus huhmini, discovered on Aphae Island in South Korea. The fossil, the first from the country to include skull parts, reveals a turkey-sized animal that likely had a fluffy appearance and an omnivorous diet. The findings, led by Jongyun Jung, were published on March 19 in the journal Fossil Record.
