Fifteen characters showed too little variation within the family--were too consistent--to be useful: Degree of ossification of the nasal septum, degree of ossification of the nasal conchs, presence or absence of a horizontal flange of the nasal septum (= floor of the nasal capsule), rostral palatines twisted or not, shape of orbital process of quadrate bone, shape of retroarticular process of mandible, completeness of rostral palate, shape of process 7b of mandible, shape of pseudotemporal process of mandible, presence or absence of a free lacrimal bone, degree of fusion of pterygoid-palatine junction, ratio of ulna length: humerus length, ratio of tibiotarsus length: tarsometatarsus
length, degree of squamosal inflation, shape and size of the rostral end of the vomer.
Despite quantitative differences in morphology among island and mainland populations, mass, wing chord, and tarsometatarsus
lengths for all populations fell within the range of values reported by Wheelwright and Rising (1993) for "typical" Savannah sparrows (Table 1).
A right distal tibiotarsus and complete left tarsometatarsus
(SBMNH 750) agree in all respects to bones of this species.
367 BA SD RA of RA of (wk) (b/ tarsometatarsus tarsometatarsus
The growth rate of the tarsometatarsus
bone in birds.
Radiographs showed soft tissue swelling at the right distal tarsometatarsus
and digits, with a smoothly marginated periosteal reaction primarily affecting the phalanges of digit 2, best seen on the dorsoplantar projection (Fig 2).
Guthrie suggested (2002) that if differential preservation is occurring in avian fossil elements, tarsometatarsus
elements would be preserved more than femur or coracoid elements.
1 mm), with foot and tibiotarsus held perpendicular to tarsometatarsus
, measuring the distance between the extreme bending points (Alatalo and Lundberg, 1986).
To illustrate, in figure 4 I have superimposed on their developmental trajectory the allometric relationship found for the tarsometatarsus
(TMT) and carpometacarpus (CMC) in adults.
In avian species, the most common sites for pelvic limb amputation are transection of the proximal tarsometatarsus
04 times larger than females for wing length, culmen length, and tarsometatarsus
length and approximately 1.
A separate oscillometric noninvasive blood pressure device (petMAP graphic, Ramsey Medical Inc, Tampa, FL, USA) was used with a size 8-cm cuff (cuff width approximately 40% of the circumference of the limb) placed around the right hind limb proximal to the tarsometatarsus
