“…Similar procedures were followed for: the neural arches and centra of the cervical, thoracic, sacral, and caudal regions; ribs of the trunk and sacral region; serial elements of the manus and pes (e.g., metacarpals/-tarsals, phalanges, and proximal and distal autopodial elements); and costals. We compared our data for P. sinensis with those of six additional taxa obtained from the literature: Spiny soft-shell turtle (Apalone spinifera [Sheil, 2003]); common and alligator snapping turtles (Chelydra serpentina [Sheil and Greenbaum, 2005] and Macrochelys temminckii [Sheil, 2005]); American alligator (Alligator mississippiensis [Rieppel, 1993b]); Japanese quail (Coturnix japonica [Nakane and Tsudzuki, 1999]); and common wall lizard (Lacerta vivipara [Rieppel, 1992]). …”

We investigated the development of the whole skeleton of the soft-shelled turtle Pelodiscus sinensis, with particular emphasis on the pattern and sequence of ossification. Ossification starts at late Tokita-Kuratani stage (TK) 18 with the maxilla, followed by the dentary and prefrontal. The quadrate is the first endoskeletal ossification and appears at TK stage 22. All adult skull elements have started ossification by TK stage 25. Plastral bones are the first postcranial bones to ossify, whereas the nuchal is the first carapacial bone to ossify, appearing as two unstained anlagen. Extensive examination of ossification sequences among autopodial elements reveals much intraspecific variation. Patterns of ossification of cranial dermal elements are more variable than those of endochondral elements, and dermal elements ossify before endochondral ones. Differences in ossification sequences with Apalone spinifera include: in Pelodiscus sinensis the jugal develops relatively early and before the frontal, whereas it appears later in A. spinifera; the frontal appears shortly before the parietal in A. spinifera whereas in P. sinensis the parietal appears several stages before the frontal. Chelydrids exhibit an early development of the postorbital bone and the palatal elements as compared to trionychids. Integration of the onset of ossification data into an analysis of the sequence of skeletal ossification in cryptodirans using the event-pairing and Parsimov methods reveals heterochronies, some of which reflect the hypothesized phylogeny considered taxa. A functional interpretation of heterochronies is speculative. In the chondrocranium there is no contact between the nasal capsules and planum supraseptale via the sphenethmoid commissurae. The pattern of chondrification of forelimb and hind limb elements is consistent with a primary axis and digital arch. There is no evidence of anterior condensations distal to the radius and tibia. A pattern of quasi- simultaneity is seen in the chondrogenesis of the forelimb and the hind limb.

“…In the turtles, the nasal and lacrimal are coded as last elements, as these two bones are absent in these species. In all outgroups except for the Japanese quail (Nakane and Tsudzuki 1999), the orbitosphenoid is coded as last element, given its absence. Sidor (2001) considered the orbitosphenoid a neomorph of Mammalia, although it should be noted that a bone of the same name (probably not homologous) is identified in other tetrapods (e.g., Bellairs and Gans 1983).…”

We analyzed a comprehensive data set of ossification sequences including seven marsupial, 13 placental and seven sauropsid species. Data are provided for the first time for two major mammalian clades, Chiroptera and Soricidae, and for two rodent species; the published sequences of three species were improved with additional sampling. The relative timing of the onset of ossification in 17 cranial elements was recorded, resulting in 136 event pairs, which were treated as characters for each species. Half of these characters are constant across all taxa, 30% are variable but phylogenetically uninformative, and 19% potentially deliver diagnostic features for clades of two or more taxa. Using the conservative estimate of heterochronic changes provided by the program Parsimov, only a few heterochronies were found to diagnose mammals, marsupials, or placentals. A later onset of ossification of the pterygoid with respect to six other cranial bones characterizes therian mammals. This result may relate to the relatively small size of this bone in this clade. One change in relative onset of ossification is hypothesized as a potential human autapomorphy in the context of the sampling made: the earlier onset of the ossification of the periotic with respect to the lacrimal and to three basicranial bones. Using the standard error of scaled ranks across all species as a measure of each element's lability in developmental timing, we found that ossification of early, middle, and late events are similarly labile, with basicranial traits the most labile in timing of onset of ossification. Despite marsupials and placental mammals diverging at least 130 Ma, few heterochronic shifts in cranial ossification diagnose these clades.

“…Although this is the first time this dissociation in ossification sequence from chondrification sequence has been noted for cervical ribs in birds, this is not exceptional when the entire skeleton is considered. Loss of an anterior to posterior gradient in the ossification of the axial skeleton is not uncommon among amniotes (Strong, 1925;Rieppel, 1993;Nakane and Tsudzuki, 1999;Sheil, 2003;Blom and Lilja, 2004;Maxwell, 2008).…”

“…For instance, the proximal phalanx of metacarpal IV ossifies before the mesethmoid (Table 2). Although this phalanx ossifies prior to hatching in the Domestic Turkey (M. gallopavo), the Japanese Quail (Coturnix coturnix) (Nakane and Tsudzuki, 1999;Maxwell, 2008), and variably so in G. gallus (Hogg, 1980), it ossifies quite late in galliforms and is always preceded by the mesethmoid. Both S. mollissima and A. platyrhynchos also ossify metacarpal II prior to hatching, which has not been reported for birds.…”

Ossification sequences are poorly known for most amniotes, and yet they represent an important source of morphogenetic, phylogenetic, and life history information. Here, the author describes the ossification sequences of three ducks, the Common Eider Somateria mollissima dresseri, the Pekin Duck Anas platyrhynchos, and the Muscovy Duck Cairina moschata. Sequence differences exist both within and among these species, but are generally minor. The Common Eider has the most ossified skeleton prior to hatching, contrary to what is expected in a subarctic migrant species. This may be attributed to a tradeoff between growth rate and locomotory performance. Growth rate is higher in hatchlings with more cartilaginous skeletons, but this may compromise locomotion. No major ossification sequence differences were observed in the craniofacial skeleton when compared with Galliformes, which suggests that the influence of adult morphology on ossification sequence might be relatively minor in many taxa. Galliformes and Anseriformes, while both highly ossified at hatching, differ in the location of their late-stage ossification centers. In Anseriformes, these are most often located in the appendicular skeleton, whereas in Galliformes they are in the thoracic region and form the ventilatory apparatus.
