The cave bear was a large bear species that lived in Europe and Asia during the Pleistocene era, weighing up to 1 ton for males and 225-250kg for females, and became extinct due to the Last Glacial Maximum cooling period. The duck marine was a rare duck species found only on three Pacific islands that disappeared due to habitat loss from draining marshlands for agriculture and damage during World War II, with the last pair observed in the wild. Extinct animals mentioned in the document include the cave bear and duck marine, which disappeared due to climate changes or human activities like warfare and conversion of wetlands to farmland.

What was it? The cave bear was a species of bear that mostly lived in Europe, but some lived
in Asia during the Pleistocene. They had similar skeletal structure as brown bears have
nowadays. The average weight for males was from 350kg to 600kg and some could even have
a weight of 1 ton, while the average weight for females was from 225kg to 250kg.
Why did it disappear? They became extinct because of the Last Glacial Maximum. This was
the most recent time during the Last Glacial Period when ice sheets were at their greatest
extent.
This may be how it
looked like in real life.

3. THE DUCK MARINE
It is a species that was found only on three small
Pacific islands.
Habitat loss due to drainage of marshland for
agriculture and damage to islands during the Second
World War were the main causes that have led to the
disappearance of this species of wild duck.
The last pair of ducks were observed in the wild.
