Comment on "Small bilaterian fossils from 40 to 55 million years before the Cambrian"Stefan Bengtson
CA Inst Technol, Pasadena
Science 306:1291; author reply 1291. 2004
The controversial "Cambrian" fossils of the Vindhyan are real but more than a billion years olderStefan Bengtson
Department of Palaeozoology, Swedish Museum of Natural History, SE 104 05 Stockholm, Sweden
Proc Natl Acad Sci U S A 106:7729-34. 2009..Like Neoproterozoic phosphorites a billion years later, the Vindhyan deposits offer important new insights into the nature and diversity of life, and in particular, the early evolution of multicellular eukaryotes...
Fossilized nuclei and germination structures identify Ediacaran "animal embryos" as encysting protistsTherese Huldtgren
Department of Palaeozoology, Swedish Museum of Natural History, Stockholm, Sweden
Science 334:1696-9. 2011..They represent an evolutionary grade in which palintomic cleavage served the function of producing propagules for dispersion...
Phase-contrast X-ray microtomography links Cretaceous seeds with Gnetales and BennettitalesElse Marie Friis
Department of Palaeobotany, Swedish Museum of Natural History, SE 104 05 Stockholm, Sweden
Nature 450:549-52. 2007..This has significant consequences for hypotheses of seed plant phylogeny by providing support for key elements of the controversial anthophyte hypothesis, which links angiosperms, Bennettitales and Gnetales...
Cellular and subcellular structure of neoproterozoic animal embryosJames W Hagadorn
Department of Geology, Amherst College, Amherst, MA 01002, USA
Science 314:291-4. 2006..Many of these features are compatible with metazoans, but the absence of epithelialization is consistent only with a stem-metazoan affinity for Doushantuo embryos...
Synchrotron X-ray tomographic microscopy of fossil embryosPhilip C J Donoghue
Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK
Nature 442:680-3. 2006..SRXTM provides a method of non-invasive analysis that rivals the resolution achieved even by destructive methods, probing the very limits of fossilization and providing insight into embryology during the emergence of metazoan phyla...
Discoidal impressions and trace-like fossils more than 1200 million years oldBirger Rasmussen
Centre for Global Metallogeny, Department of Geology and Geophysics, University of Western Australia, Crawley, Western Australia 6009, Australia
Science 296:1112-5. 2002....

Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK
Evol Dev 9:206-7. 2007
Palaeontology: a ghost with a biteStefan Bengtson
Nature 442:146-7. 2006
Deciphering the fossil record of early bilaterian embryonic development in light of experimental taphonomyNeil J Gostling
Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK
Evol Dev 10:339-49. 2008..The preponderance of fossilized embryos of direct developers should not be used in evidence against the existence of indirect development at this time in animal evolutionary history...
Fossilized embryos are widespread but the record is temporally and taxonomically biasedPhilip C J Donoghue
Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK
Evol Dev 8:232-8. 2006..Together, these biases must be considered seriously in attempts to use the fossil record to arbitrate between hypotheses of developmental and life history evolution implicated in the origin of metazoan clades...
