Computed tomography scan, ventral view, of a 3-dimmensional musculoskeletal reconstruction demonstrating the sternum bifurcation (white arrow) and the fusion of the
furcula and the sternum (black arrow) of the hatch-year red-tailed hawk described in Fig 1.
IV, head, coxa, trochanter, femur, body and anterior and posterior face of
furcula (manubrium and dens).
Avian
furcula morphology may indicate relationships of flight requirements among birds.
El orden agrupa a los colembolos de cuerpo alargado, con apendices generalmente largos (antenas, patas y
furcula).
Between her neck and ribcage, Sue also has an enormous forked wish bone, or
furcula: the first ever found in a T.
Furcula very reduced, dens with 3 setae, mucro minute or lacking.
Furcula absent (posterior margin of 10th abdominal segment is the transverse divide of the supra-anal plate).
The
furcula was asymmetrical because the left clavicle was slightly thinner and more radiolucent than the right and was also slightly deviated to the right side.
8, electro scanning microphotographs of
furcula posterior view; and 9, mucro antero-median view.
Medial carina of the second abdominal segment of the female devoid of any anterior tubercle (differentiates from Pararhicnoderma.) Tenth abdominal tergite completely divided; male
furcula absent.
Furcula represented by two, digitiform, robust projections as long as broad, with rounded apex.
The
furcula is represented by short, subtriangular, rounded lobes and the male supra-anal plate is subtriangular.
