Palaeontologists have found new evidence that the early ancestors of amphibians, reptiles and mammals did not have a larval stage with external gills like modern frogs or salamanders
A Vietnam Veteran Collected Fossils for 66 Years. One, Mislabeled 'Baby Lamprey,' Made Paleontologists Reconsider How Vertebrates Moved From Water to Land
The fossil turned out to be a hatchling of a crocodile-like creature, and it suggests, according to a new study, that early animals did not use metamorphosis to evolve to dwell on land
A New Fossil Discovery Just Rewrote 150 Years of Evolutionary Theory
🌘Subscribe to 404 Media to get The Abstract, our newsletter about the most exciting and mind-boggling science news and studies of the week. Ancient fossils have revealed that the earliest animals to walk on land more than 300 million years ago did not experience a metamorphosis similar to modern amphibians, a discovery that rewrites the evolutionary history of terrestrial vertebrates, according to a study published on Thursday in Science.Humans…
These 300-million-year-old baby fossils just turned a major evolution theory upside down
Ancient fossilized babies of crocodile-like predators are rewriting evolutionary history. Previously, scientists believed early land animals hatched, underwent a tadpole phase, and then transformed, much like modern amphibians. However, new discoveries reveal these early tetrapods skipped the tadpole stage, suggesting their life cycles were more akin to fish or mammals, fundamentally altering our understanding of how life conquered land.
Researchers at the Field Museum of Natural History have described fossils of embolomeres embryos, crocodile-like predators that inhabited rivers and swamps between 350 and 280 million years ago. The discovery suggests that these animals did not undergo metamorphosis as previously thought, challenging the traditional view of the evolution of terrestrial vertebrates.

The discovery of fossils of preserved tetrapod babies in Mazon Creek, United States, is messing with one of the most well-known stories of evolution. For a long time, scientists have imagined that the first vertebrates of four members have grown in a way similar to modern amphibians, going through a phase similar to girinos before becoming...
