Tooth fossil, SEM
Tooth fossil. Coloured scanning electron micrograph (SEM) of a fossilised canine tooth of the extinct Puerto Rican shrew (Nesophontes edithae). This shrew was endemic (localised) to western Puerto Rico and fed mainly on insects. It became extinct after the introduction of rats and the destruction of its forest habitat. Fossilisation is a process in which organic matter is slowly replaced by minerals, preserving the form of the original tissue. This fossil dates back to the Late Pleistocene epoch (about 126, 000 years ago)

EDITORS COMMENTS
This print showcases a tooth fossil that tells a poignant tale of the past. The coloured scanning electron micrograph (SEM) reveals the intricate details of a canine tooth belonging to the now-extinct Puerto Rican shrew, Nesophontes edithae. Endemic to western Puerto Rico, this tiny creature thrived on insects until its unfortunate demise due to rat introduction and habitat destruction. Dating back approximately 126,000 years ago during the Late Pleistocene epoch, this fossil serves as a window into history. Fossilisation is an extraordinary process in which organic matter gradually transforms into minerals while preserving the original tissue's form. The grooves and sharpness of this tooth are testament to its once vital role in hunting and survival. As we observe this single relic from prehistoric times, it evokes feelings of wonder and curiosity about our planet's rich biological heritage. It reminds us how fragile ecosystems can be when faced with invasive species and environmental changes. The false-coloured SEM image adds depth and vibrancy to this scientific marvel, allowing us to appreciate every minute detail captured by the scanning electron microscope. This photograph not only celebrates paleontology but also highlights the importance of understanding our natural world's complex dynamics. Courtesy of Science Photo Library, this remarkable print invites us to reflect on both Earth's ancient past and our responsibility towards preserving its delicate balance for future generations.
