Embryonic identity crisis
Article Abstract:
The Parapandorina and Megasphaera fossils found from the Doushantuo phosphorite rocks of southern China are the oldest unequivocal animal fossils, which as embryos provided a glimpse of animal embryology. Evidence shows that these fossils with features thought to be indicative of animal embryos could be those of bacteria, based on comparisons with Thiomargarita, a giant sulphur bacteria that live in seafloor along the Namibian coast.

Synchrotron X-ray tomographic microscopy of fossil embryos
Article Abstract:
Synchrotron-radiation X-ray tomographic microscopy (SRXTM) is applied to obtain complete three-dimensional recordings of the fossilized embryos at submicrometre resolution. The SRXTM has provided a method of non-invasive analysis that is better than the resolution achieved even by destructive methods, probing the very limits of fossilization and providing insight into embryology during the emergence of metazoan phyla.

Fossil embryos from the middle and late Cambrian period of Hunan, south China
Article Abstract:
Fossil embryos provide a crucial test of the assumption that, life histories of living taxa are representative of their antecedents. A collection of embryos from the Middle and Late Cambrian period of Hunan, south China, is presented.
