A mangrove is a shrub or tree that grows in coastal saline or brackish water, first appearing during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates.
The San Pedro Martir mangrove forest was once on the shores of a vast ocean where the temperature was much warmer, but is now situated more than 170 kilometres inland due to climatic changes in sea levels. The forest offers a snapshot of the ancient past, allowing scientists to understand how environments adapted to changing sea levels as the global climate changed...
In a paper published in PNAS by the University of California, the researchers took genetic and geological samples to work out exactly how the mangroves made it from the coast to the river.
Their study found that the San Pedro Martir mangroves are related to those found at the coastal Términos Lagoon in southern Mexico, becoming a divergent group separated during a period of history known as the Eemian or Last Interglacial.
At the time, the world temperature was three to five degrees °C warmer than present day, causing icesheets around the world to melt that resulted in sea levels rising by six to nine metres.
As the coastal regions of Mexico is relatively flat, the sea level changes submerged vast areas of land, with geological samples of aquatic shells and rounded pebbles indicating that much of the land was underwater during the Eemian.
At the time, far from being isolated from the sea, the mangroves of the San Pedro Martir River were once on the coastline of a large ocean. Following cooling temperatures as the last Ice Age began the sea levels declined, leaving the mangroves isolated in the river.

Oh the mangrovity!!
Is that picture for real? A real photograph? That’s a very strange picture I see no roads, no electricity, no people, no animals, no vehicles, etc. Can’t believe that’s a real picture.
I suppose they didn’t even consider “seeds”.....................
It’s real.
Ok, Globull Climate Change idiots, could you tell us how the climate changed without anyone driving SUVs? Greta, are you going to say how WE did it? 🤓
what were the dates on these mangroves?
It is real-there are many, many places outside of cities and towns where there are no vehicles, few/no electrical lines readily visible, etc-they are called wilderness areas...
Thanks for the article-with all the evidence showing that the climate has and will always change, you’d think no intelligent person would think humans can deter that...
Those damn oil companies and their fossil fuels...
Hhmm... wait a minute...
I’m not sure dates grow on mangroves. Wait, what?
Well put.
Gracias, Senor...
The article talks about the these mangroves growing during the last interglacial. (before suggesting that the groves may have been from another period.)
When was the last interglacial?
Grovy.
