“…Callitrichids also deviate from other anthropoids in having less developed deciduous and permanent dentition at birth (Smith et al, ), and they develop and erupt their teeth earlier than other anthropoids (Macho, , Smith, ) consistent with our hypothesis posed here. However, it is important to note that generalizing the hypothetical relationship between dental development and body size distills callitrichid development down to overall growth rate, and it has been shown that growth rates of the skeleton and dentition vary among callitrichids (Glaser, ; Smith et al, ), although they do tend to have a slower growth rate than other anthropoids (e.g., Montgomery and Mundy, ). Overall, the timing of dental development likely has a phylogenetic signal in primates comparable to what is seen for other ontogenetic dental traits, such as permanent tooth eruption sequence (Monson and Hlusko, ), with callitrichids deviating from other anthropoids in having slower growth rates and earlier tooth eruption (Smith, ; Macho, ; Montgomery and Mundy, ).…”

A growing body of literature demonstrates that genetic patterning mechanisms underlie the relative proportions of the mammalian postcanine dentition with the third molar being key to understanding variation within the molar row. With this relatively recent insight, there has been renewed interest in mammalian taxa that have lost the third molars. Within platyrrhines, the marmosets and tamarins (Callitrichidae family) are characterized by small body size, claw-like nails, twinning, and reduced molar number. Small body size is hypothesized to have resulted in the third molar being crowded out of the jaws leading to its evolutionary loss in this family. To further explore this hypothesis, we measured the cranium and dentition of 142 individuals spanning all five platyrrhine families. These data reveal that callitrichids have a significantly smaller proportion of mandibular postcanine tooth row length relative to other platyrrhines, refuting the "crowding out" hypothesis. However, postcanine tooth row length is significantly correlated with mandibular length and cranial length (P < 0.01) across all platyrrhines providing evidence for a strong allometric association between postcanine tooth row length and body size more generally. The small body size that characterizes callitrichids results in part from slower prenatal growth rates. Given the allometric relationship between postcanine tooth row length and body size, reported here and in previous studies, we hypothesize that the evolutionary loss of the third molars in callitrichids results from the inhibition of third molar development as a consequence of the slower prenatal growth rates associated with small body size in this family.

“…A number of studies investigated ossification sequences in mammalian taxa, particularly in the first half of the 20 th Century (Adams, 1992; Glaser, 1970; Hodges, 1953; Johnson, 1933; Mall, 1906; O’Rahilly & E., 1975; O’Rahilly & Gardner, 1972; Petri, 1935; Prochel, Vogel & Sanchez‐Villagra, 2004; Sánchez‐Villagra, 2002; Schaeffer, 1931, 1934; Strong, 1925). Curgy (1965) reviewed the literature on the ossification sequences of the entire skeleton of mammalian taxa, including carnivores, ungulates, rodents, and primates.…”

Ossification patterns in the tetrapod limb – conservation and divergence from morphogenetic events

Two different patterns of the condensation and chondrification of the limbs of tetrapods are known from extensive studies on their early skeletal development. These are on the one hand postaxial dominance in the sequential formation of skeletal elements in amniotes and anurans, and on the other, preaxial dominance in urodeles. The present study investigates the relative sequence of ossification in the fore- and hindlimbs of selected tetrapod taxa based on a literature survey in comparison to the patterns of early skeletal development, i.e. mesenchymal condensation and chondrification, representing essential steps in the late stages of tetrapod limb development. This reveals the degree of conservation and divergence of the ossification sequence from early morphogenetic events in the tetrapod limb skeleton. A step-by-step recapitulation of condensation and chondrification during the ossification of limbs can clearly be refuted. However, some of the deeper aspects of early skeletal patterning in the limbs, i.e. the general direction of development and sequence of digit formation are conserved, particularly in anamniotes. Amniotes show a weaker coupling of the ossification sequence in the limb skeleton with earlier condensation and chondrification events. The stronger correlation between the sequence of condensation/chondrification and ossification in the limbs of anamniotes may represent a plesiomorphic trait of tetrapods. The pattern of limb ossification across tetrapods also shows that some trends in the sequence of ossification of their limb skeleton are shared by major clades possibly representing phylogenetic signals. This review furthermore concerns the ossification sequence of the limbs of the Palaeozoic temnospondyl amphibian Apateon sp. For the first time this is described in detail and its patterns are compared with those observed in extant taxa. Apateon sp. shares preaxial dominance in limb development with extant salamanders and the specific order of ossification events in the fore- and hindlimb of this fossil dissorophoid is almost identical to that of some modern urodeles.

“…Special attention was given to the hand/wrist skeleton because this anatomical area contains a large number of developing osseous centers and is commonly used as a general index of skeletal development [Galliari, 1988;Glaser, 1970;Phillips, 1976;Schultea et al, 1983;Tanner et al, 1972;Thurm et al, 1975;Watts, 1971Watts, , 1975. The state of secondary ossification was classified into three stages of development, as shown in Fig.…”

The phylogenetic affinities of the neotropical Goeldi's monkey (Callimico goeldii) have long been a matter of debate. Whereas most morphological evidence appears to place Callimico in a sister group position relative to the Callitrichidae, genetic studies place C. goeldii within the Callitrichidae and suggest that it is more closely related to marmosets than to tamarins. The present study presents the first radiographic analysis comparing the secondary limb bone ossification of newborn C. goeldii with representatives of the marmosets (Callithrix jacchus) and tamarins (Saguinus oedipus). The state of secondary ossification of the epiphysis and short bones is classified into three different ontogenetic stages. Our results reveal that in terms of the number of ossification centers, C. goeldii is significantly closer to C. jacchus than to S. oedipus. This is the first morphological study to support the findings of molecular studies, and the results suggest that C. goeldii is more closely related to marmosets than to tamarins.
