Abstract
Many of the rarest prehistoric bones found by archaeologists are enormously precious and are considered to be part of our cultural and historical patrimony. Radiocarbon dating is a well-established technique that estimates the ages of bones by analysing the collagen still present. However, this method is destructive, and its use must be limited. In this study, we used imaging technology to quantify the presence of collagen in bone samples in a non-destructive way to select the most suitable samples (or sample regions) to be submitted to radiocarbon dating analysis. Near-infrared spectroscopy (NIR) that was connected to a camera with hyperspectral imaging (HSI) was used along with a chemometric model to create chemical images of the distribution of collagen in ancient bones. This model quantifies the collagen at every pixel and thus provides a chemical mapping of collagen content. Our results will offer significant advances for the study of human evolution as we will be able to minimise the destruction of valuable bone material, which is under the protection and enhancement of European cultural heritage and thus allow us to contextualise the valuable object by providing an accurate calendar age.

Abstract
The complete mitogenome sequence of Eothenomys eleusis Thomas 1911 was determined using PCR. A circular double-stranded structure makes up the mitochondrial genome of E. eleusis. The complete length of the mitochondrial genome is 16,419 bp. The mitochondrial genome of E. eleusis included 13 protein-coding genes, 1 control region, 22 tRNA genes, 2 rRNA genes and 1 origin of L strand replication. The total base composition of E. eleusis mitochondrial genome was A (32.6%), T (26.3%), G (13.6%) and C (27.5%). We found significant A-T skew in base composition, especially in control regions and protein-coding genes. E. eleusis was supported by bootstrap values of 100%. This study verifies the evolutionary status of E. eleusis in Myodini tribe of Cricetidae at the molecular level. The mitochondrial genome would be a significant supplement for the E. eleusis genetic background.
