What people are saying
The overall sentiment demonstrates curiosity and support, with users describing the extinction event as 'neat', 'wild', and 'fantastic mystery,' which shows enthusiasm. The tone, combining wonder and inquiry, along with mentions of possible causes like heavy metals or cetaceans, indicates that the publication stimulates active interest and discussion about its implications.
Most discussions accept the significance of the discovery, with some expressing surprise or intrigue, reflecting general support and acknowledgment of the research.
Participants show high interest, frequently mentioning how the discovery is new, fascinating, or surprising, indicating engagement with the topic.
Comments include personal reactions, questions about external factors, and references to related research, showing moderate but meaningful engagement.
While not overwhelming, the discussions highlight that the research sparks curiosity and could influence understanding of marine extinction events, suggesting a moderate impact.
Abstract in brief
- Shark populations have drastically decreased in recent years due to overfishing and human activity, leading to concerns about the long-term effects on marine ecosystems.
- Research indicates there was a significant shark extinction event around 19 million years ago during the early Miocene, with a reduction in shark abundance by over 90% and morphological diversity by 70%.
- This extinction occurred without any global climate event influencing it and happened several million years prior to the emergence of the large, migratory sharks that now dominate ocean environments.

Nowadays, we're pretty confident about how the dinosaurs died out, but there are still other extinctions throughout Earth's history that remain unsolved. https://t.co/A7gvZkaL7C https://t.co/sVewAhZ9Kt

An early Miocene extinction in pelagic sharks https://t.co/gzxpklVluP . I can only surmise that ancient sharks reached a biological threshold whereby their bodies could tolerate only a certain level of mercury .Their muscle mass deteriorated having the same effect as zero gravity
