摘要
| 描述 | Radius microstructure of the holotype of Corythoraptor jacobsi gen. et sp. nov. (JPM-2015-001) viewed with reflected light microscopy. (a) Transversal section of the midshaft showing five growth lines (red arrows A to E) present in the middle-to-outer cortex. Note that growth line spacing decreases periosteally. (b) Close-up of the outer cortex with three growth lines (C to E). Note avascular layers (annuli) deposited prior to and after darker undulating line (line of arrested development, LAG). Primary bone is mostly preserved external to the growth line D. Secondary osteons partly obliterate the growth line C. (c) Close-up of the middle cortex with two growth lines (A and B). Growth line A consists of an ill-defined LAG followed by laminar bone (annulus). Growth line B comprises a darker line (LAG) and lighter avascular layer (annulus). Note several generations of overlapping secondary osteons are present. (d) The last growth cycles delimited by growth lines C through E. (e) Interior margin of the cortical bone with a thick deposition of endosteal laminar bone. The blue arrow points to the resorptive margin. Abbreviations: an, annulus; elb, endosteal laminar bone; LAG, line of arrested growth; lb, laminar bone; mc, medullary cavity; nvc, neurovascular canal; osla, osteonal laminae; po, primary canal; rl, resorption line; so, secondary osteon. |
