Fig. 1. Larval development in the Early Cretaceous pipid Thoraciliacus rostriceps from Makhtesh Ramon, Israel. A.

Fig. 5 in Patterns of larval development in Cretaceous pipid frogs
Fig. 5. Comparison of the relative sequence of some developmental events of the skull in the Cretaceous Shomronella, Oligocene Palaeobatrachus, and Recent Xenopus, with the Paleozoic Apateon (Temnospondyli: Branchiosauridae), primitive recent caudates Ranodon and Salamandrella (Cryptobranchoidea: Hynobiidae), and neotenic caudate Ambystoma (Ambystomatidae). Bones that are retained in the anurans are in bold. Because of differences in definition of metamorphosis among various authors, and because of different definition of developmental stages in the Paleozoic amphibians, caudates and anurans, comparison in terms of exactly corresponding anatomical stages is not possible. The most objective for staging in the amphibians is formation of the mouth, beginning of metamorphosis (associated with reduction of gills in caudates, development of the limbs in anurans), and the end of metamorphosis (loss of tail in the anurans). Data on Apateon from Schoch (1998), on the caudates from Lebedkina (2004), and on Palaeobatrachus from Roček (2003b).

The photo taken by Zeiss Stemi 2000C stereomicroscope (A1). The photo taken by means of the image analysing software "Image Pro Plus" (A2). B.

Rudimentary frontoparietals. D. Approximately same stage as the previous, dorsal view (HUJZ−13132). Scale bars 5 mm.
Fig. 3 in Effect of forest microhabitat and larval stage on overwintering survival, development, and phenology of Spathius galinae (Hymenoptera: Braconidae), biological control agent of emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae)
Fig. 3. Proportion of dead (A) and diapaused (B) Spathius galinae by stage at time of deployment, and overwintering microhabitat.

Fig. 2 in Effect of forest microhabitat and larval stage on overwintering survival, development, and phenology of Spathius galinae (Hymenoptera: Braconidae), biological control agent of emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae)
Fig. 2. Deployment jar for logs containing emerald ash borer larvae parasitized by Spathius galinae. Logs were inserted in floral foam in 3.8 L polyethylene terephthalate jar with 2 mesh cutouts for ventilation and excess water drain- age. The jar was attached to the tree by resting the bottom of the jar on 2 nails hammered into the tree while a length of wire wrapped around the 2 nails on either side of the jar. Another wire looped around the neck of the jar and was fastened to the nail at the top. Water was added to the jars as needed to ensure adequate hydration of the logs and larvae.
