10 extinct plants with a wonderful history

Araucarioxylon arizonicum

He traveled via Forest Forest, and you may see remnants from 200 to 250 million years old Araucarioxylon arizonicum The trees that flourished during the Triassic period. So that some of them are preserved as rocky, carved by the indigenous people living in the region 8,000 years ago.

Today, the National Garden is located in the provinces of Navajo and Abshi in the northeast of Arizona. Other trees from Araucaria There is still a gender that is around the world – it may be more famous on Norfolk Pine Island.

ATRIPEX TULARENSIS

Known as the common name Tulare Saltbush or BakerSfield Saltbush, ATRIPEX TULARENSIS The last time was seen in 1991. It was an annual herb that grew in alkaline salt basins at the southern end of the Central Valley in California until it was transferred to extinction by expanding agriculture.

With the growth of the central valley to become a global agricultural leader, farmers and communities drain the internal lakes and took advantage of deep groundwater layers faster than the coastal flow that could be fill in it, and they are forbidden ATRIPEX TULARENSIS From water.

Calmet

Calmet It has become extinct since the era of Al -Barami about 250 million years ago, but his colleagues are members of the sex of a ponytail (ExiseumIt is still growing in the world’s swamps. Like a modern ponytail, Calmet It grew in a forest of roots crawling underground, sending hollow, ribs, similar to bamboo that grew to 100-160 feet (30-50 meters).

The prosperity during the carbon period, when both the Earth’s land blocks were all associated with the name of Pangea, magnet Excavations can be found on all continents.

Cooksonia

Cooksonia –The oldest known blood vessels, which means that its tissues that performed water, weaving and nutrients – dates back to about 425 million years. Like other early plants to develop from green algae, Cooksonia Lack of papers. How the sun energy is still the subject of scientific debate.

Stems Cooksonia It is Make it revolutionary. With water delivery stems, Cooksonia There is no longer a need to stay immersed in the water. Dry lands can colonize and pave the road until the animals later appear in the sea.

Franklina Autamaha

Franklina Autamaha It has become extinct in the wilderness since the early nineteenth century and was only present in agriculture. Born in the southeastern United States, it was first known to non -indigenous Americans when he was identified in 1765.

It was named Benjamin Franklin, the tree survived only for 13 years, after the last time was seen in the wilderness in 1803. in the late eighteenth century, the reasons for its extinction were rare. Today, only cultivated samples are because the tree was fortunate enough to have flowers that satisfy the human eye.

Glossopteris

Glossopteris It is one of the few success stories of bad Newfoundland The mission led by Robert Falcon Scott, who froze to death in Antarctica with his crew. When their bodies were later discovered, the 270 million years old fossils were returned to London. Glossopteris It was identified, which proves that the Antarctica was once linked to other continents and covered with a vegetarian life, confirming the theory of classes.

Glossopteris It is an early gym, a tree that produces seeds that include coniferies and cicad.

Nesiota Eliptical (ST. Helena Olive)

You might think that one of the world islands, Saint Helena in the South Atlantic (where Napoleon was one day), will be a safe place for the original plants. However, the arrival of the Portuguese in 1502 led to the extinction of many original plants, Sant Helen, due to the removal of forests and the input of goats. The last remaining tree died in agriculture in 2003.

Orbexilum Stipulatum

The factory relied on Boufalo’s grazing, who was once wandering in the Ohio River Valley. I took out excessive fishing from buffalo out of the region and with it Orbexilum stipulatum. Benned dam on the site, immersing Rock Island, sinking the hopes of the plant’s survival.

seal

seal It is one of the most common types of plants from which fossil fuels are made. They look like Joshua trees or something from Dr. Souss’s book, seal It flourished during the carbon (or carrier) period from 300 to 360 million years.

Trees -like plants have risen on the floor of peat -forming swamps, cloned by germs present in the cones at the end of their branches. Their fossils were detected during coal mining operations around the world, from West Pennsylvania to the inner Mongolia.

Sophora Toromiro

Toromiro Tree (Sophora ToromiroIt was one day a settlement on the Easter island (RAPA NUI), but despite the efforts made to grow it from the seeds collected in the 1960s, the tree has since become extinct in the wilderness. The origins and meaning of the famous huge statues on Easter Island, Easter, remains, but also the reasons for removing forests on the island.

A mixture of excessive harvest, climatic changes and cultural developments seem intertwined with the collapse of a sustainable society. Whatever the reason and whatever the pace of change, the painful lesson of Easter Island is still the same.
