Fig. 3 in Research history, taphonomy, and age structure of a mass accumulation of the ornithopod dinosaur Dysalotosaurus lettowvorbecki from the Upper Jurassic of Tanzania
Fig. 3. Original, unopened bamboo corsets containing bones of ornithopod dinosaur Dysalotosaurus lettowvorbecki Pompeckj, 1920, from Kimmeridgian, Late Jurassic of Tendaguru, Tanzania, which are housed in the collection of fossil reptiles at the MfN. A. Stored as a stack. B. Bamboo corset in lateral view. C. Showing the labelling on the front side. The bamboo corsets are labelled with the quarry numbers and field numbers as assigned to single fossil blocks. Reference to specimens is not possible, because most of them are unprepared sediment blocks. D. CT slice exposing cross-section through bamboo corset Ig 88, bones are in white whereas lighter materials such as clay, cushioning with grass, and bamboo sticks are displaying around.
Fig. 8 in Research history, taphonomy, and age structure of a mass accumulation of the ornithopod dinosaur Dysalotosaurus lettowvorbecki from the Upper Jurassic of Tanzania
Fig. 8. Tentative reconstruction of the spatial relationships of the four bonebeds of the Ig/WJ-quarry according to the available descriptions and dates of Werner Janensch and Hans Reck. The actual shape and absolute sizes of the bonebeds are schematic and speculative. Top (A) and profile (B) views are in relation to the cardinal points. Note that the actual stratigraphic level of BB-1 in relation to BB-2 is uncertain (double headed arrow). The dotted ellipses show the approximate position of the large, possibly sauropod, bones found in September 1912 within the otherwise bone-free layer in between BB-3 and BB-4 including a scapula and a cervical vertebra. BB, bonebed. See Fig. 7 for comparison.

Fig. 3 in Age Structure In A Declining Population Of Rana Temporaria From Northern Italy
Fig. 3. Diaphyseal cross-sections of phalanges of Rana temporaria females. (a) Individual, 70 mm in body length, with 1 visible LAG plus one confluent with the outer margin of periosteal bone. Some false lines are also present. (b) Individual, 73.2 mm in body length, with 2 visible LAGs plus one confluent with the outer margin of periosteal bone. (c) Individual, 85.7 mm in body length, with 5 LAGs. (d) Individual, 101 mm in body length, with 7 LAGs. (e) Individual, 120 mm in body length, with the first 4 but not the peripheral LAGs clearly distinguishable. (f) Same individual as in the previous figure but adjacent section at higher magnification showing 6 distinct LAGs at the periphery of periosteal bone. Based on these observations it is concluded that this frog had 10 LAGs. Abbreviations: EB = endosteal bone; MC = medullar cavity; RL = reversal line; VC = vascular canal. Arrows indi-
Fig. 2 in Age Structure In A Declining Population Of Rana Temporaria From Northern Italy
Fig. 2. Diaphyseal cross-sections of phalanges of Rana temporaria males. (a) Juvenile, 50.1 mm in body length, without LAGs. (b) Individual, 63 mm in body length, with 1 visible LAG plus one nonvisible probably because it is confluent with the outer margin of periosteal bone. (c) Individual, 74.7 mm in body length, with 6 LAGs. (d) Same individual as in Fig. 2c but at higher magnification. 5 LAGs can be more easily counted in the ridge at the periphery of periosteal bone. (e) Individual, 85.2 mm in body length, with 8 LAGs. (f) Individual, 89 mm in body length, with 10 LAGs, of which the peripheral are very close to each other.
