The developing skeleton of a pelobatid frog, Spea bombifrons, is described based on a series of 81 cleared‐and‐stained tadpoles and juveniles. Most limb and limb‐girdle elements commence ossification premetamorphically, along with the parasphenoid, frontoparietals, exoccipitals, and vertebral column, during Gosner Stage 36. The chondrocranium undergoes dramatic restructuring at the beginning of metamorphosis (ca. Stage 40); and the nasal cartilages, prootics, premaxillae, nasals, maxillae… 
Skeletal development of the Mexican spadefoot, Spea multiplicata (Anura: Pelobatidae)
TLDR
The larval chondrocranium of Spea multiplicata is described, as is the development and adult morphology of the skeleton, and phenotypic plasticity within the genus and the absence of a palatine (= neopalatine) bone are discussed.
SKELETAL DEVELOPMENT AND ADULT OSTEOLOGY OF BOMBINA ORIENTALIS (ANURA: BOMBINATORIDAE)
TLDR
Comparisons of the timing of initiation of skeletal ossi- fication among several taxa suggest that this species exhibits variation in ossification sequence that may relate to precocious development of the hind limb or early onset of cranial and axial ossify.
Description of the adult skeleton and developmental osteology of the hyperossified horned frog, Ceratophrys cornuta (Anura: Leptodactylidae)
  • E. Wild
  • Biology
    Journal of morphology
  • 1997
The adult skeleton and tadpole chondrocranium of the leptodcatylid frog, Ceratophrys cornuta (Ceratophryinae), are described in detail, including the ontogenetic development of the chondrocanium and
Osteology, skeletal development, and chondrocranial structure of Hamptophryne boliviana (Anura: Microhylidae)
TLDR
The larval chondrocranium of Hamptophryne boliviana differs from those described for other microhylid taxa by the possession of a greatly expanded, fenestrate sheet of cartilage associated with the larval otic process and otic capsule.
Morphology and metamorphosis of Eupsophus calcaratus tadpoles (anura: Leptodactylidae)
TLDR
Eupsophus calcaratus, a leptodactyloid frog from the austral Andean forests of Argentina and Chile, has endotrophic, nidicolous tadpoles and heterochronic processes and truncation of larval development are related to a shorter larval life and the small size at metamorphosis.
Skeletogenesis in anurans: cranial and postcranial development in metamorphic and postmetamorphic stages of Leptodactylus bufonius (Anura: Leptodactylidae)
TLDR
Cranial and postcranial skeletogenesis, and change in skull shape through the metamorphic and postmetamorphic development of Leptodactylus bufonius are described.
Skeletal development and adult osteology of Hypsiboas pulchellus (Anura: Hylidae)
TLDR
A number of skeletal elements, including the exoccipital, frontoparietal, parasphenoid and prootic, as well as elements of the shoulder and pelvic girdles, and the phalanges, were found to vary intraspecifically regarding the relative time of their ossification within the oSSification sequence.
Postembryonic ontogeny of the spadefoot toad, Scaphiopus intermontanus (Anura: Pelobatidae): Skeletal morphology
TLDR
The record of skeletal ontogeny and muscle morphology presented herein for the herbivorous larval morph can serve as a baseline for comparisons with the ontogenY of the carnivorous larv morph of Scaphiopus.
Comparative Ontogeny of Cranial Ossification in the Spotted Salamander, Ambystoma Maculatum, and the Tailed Frog, Ascaphus Truei
TLDR
Differences in the developmental patterns of ossification in Ambystoma maculatum and Ascaphus truei reflect basic differences in the evolution of larval life histories, and geographic variation in the sequence of cranial ossify is greater than previously reported for any species of amphibian.

Variation and timing of the cranial ossification sequence of the oriental fire‐bellied toad, Bombina orientalis (Amphibia, Discoglossidae)
TLDR
The sequence of appearance of the 17 different skull bones in the oriental fire‐bellied toad, Bombina orientalis, is described, despite the poor correlation between cranial ossification and external development as assayed by Gosner stage.
The Sequence of Cranial Ossification in the California Toad, Bufo boreas (Amphibia, Anura, Bufonidae)
TLDR
A comparison of osteogenesis in field-collected and lab-reared B. boreas revealed that even though growth patterns and sequence of appearance is the same in both groups, head bones develop significantly earlier in toads collected in the field.
The larval chondrocranium of Pelodytes punctatus, with a review of tadpole chondrocrania
  • O. Sokol
  • Biology
    Journal of morphology
  • 1981
TLDR
The larval chondrocranium of the pelobatoid anuran Pelodytes punctatus was studied and is used to support the hypothesis that anuran phylogenies based on larval characters will closely resemble, in major features at least, those based solely on adult characters.
Chondrocranium and ossification sequence of Hyla lanciformis.
TLDR
The sequence of postcranial ossification is described for the first time for any species of hylid frog, and is explained in the framework of functional changes of the skull through metamorphosis.
Skull development during anuran metamorphosis: I. Early development of the first three bones to form—the exoccipital, the parasphenoid, and the frontoparietal
TLDR
Early development of the first three bones to form in the Oriental fire‐bellied toad, Bombina orientalis—the parasphenoid, the frontoparietal, and the exoccipital—are described based on examination of serial sections, which may qualify the use of whole‐mount preparations for inferring the sequence and absolute timing of cranial ossification in amphibians.
Heterochronic mechanisms of morphological diversification and evolutionary change in the neotropical salamander, Bolitoglossa occidentalis (Amphibia: Plethodontidae)
TLDR
This result supports Alberch's ('80a) prediction, based on functional analysis, that the principle adaptation to arboreality in B. occidentalis is small size; other derived morphological features are associated with the organism's truncated development and may have no adaptive significance.
