Femora, humeri, and tibiae of seven different\u2010sized individuals representing different ontogenetic stages were assessed to determine the interelement and intraskeletal histological variation within and among the tortoises. The bone histology of adult propodials consists of a highly vascularized, uninterrupted fibrolamellar bone tissue with a woven texture in the perimedullary and midcortical regions suggesting overall fast early growth. However, later in ontogeny, growth was slow and even ceased periodically as suggested by slowly formed parallel\u2010fibered bone tissue and several growth marks in the pericortical region. In juvenile individuals, fibrolamellar bone tissue is restricted to the perimedullary regions of propodials as remnants of bone formed during the earliest stages of ontogeny. The epipodials are characterized by having parallel\u2010fibered bone tissue present in their cortices; however, periodic arrests in growth are recorded at various times. Remnants of fibrolamellar bone tissue formed during early ontogeny occur in the epipodials of only a few individuals. Interelement variation is evident, in terms of variation in the orientation of vascular canals between individuals and within the same diaphyseal cross\u2010sections. Different elements show varying cross\u2010sectional geometry, which appear to be correlated with the fossorial behavior of the species. Our results show that of all the long bones, the tibia is least remodeled during ontogeny and it is therefore the best element for skeletochronology.<\/jats:p>","DOI":"10.1002\/jmor.21073","type":"journal-article","created":{"date-parts":[[2019,11,1]],"date-time":"2019-11-01T11:46:56Z","timestamp":1572608816000},"page":"1881-1899","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Long bone histology of <i>Chersina angulata<\/i> : Interelement variation and life history data"],"prefix":"10.1002","volume":"280","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5351-3702","authenticated-orcid":false,"given":"Mohd Shafi","family":"Bhat","sequence":"first","affiliation":[{"name":"Department of Biological Sciences University of Cape Town  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9786-5080","authenticated-orcid":false,"given":"Anusuya","family":"Chinsamy","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences University of Cape Town  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Parkington","sequence":"additional","affiliation":[{"name":"Department of Archaeology University of Cape Town  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,11]]},"reference":[{"issue":"58","key":"e_1_2_10_2_1","first-page":"1","article-title":"Scaling effect on the mid\u2010diaphysis properties of long bones\u2014The case of the Cervidae (deer)","volume":"103","author":"Amson E.","year":"2016","journal-title":"The Science of Nature"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-017-08536-3"},{"key":"e_1_2_10_4_1","first-page":"147","volume-title":"Petits Animaux et Societes Humaines.
