Fossil Hatchlings Challenge a Core Tetrapod Theory
Key Takeaways
- A study described by 404 Media argues early tetrapods lacked a tadpole-like larval stage.
- Researchers examined rare hatchling fossils from the fin-to-limb transition, including specimens from Mazon Creek.
- The fossils reportedly show no evidence of the external-gill-style metamorphic phase long assumed in textbook accounts.
- If confirmed, the finding would reshape how scientists interpret the developmental origins of land vertebrates.
