Trapped in 99-Million-Year-Old Amber, a Beetle With Pilfered Pollen

Trapped in 99-Million-Year-Old Amber, a Beetle With Pilfered Pollen

The distribution of related beetle cycad pollinators supports the idea that the boganiid beetle was an ancient first pollinator of cycads and that cycads were the first insect-pollinated plant. Earth's oldest pollinating insects are a bit of a mystery, but fossilised insect dung containing bits of pollen suggest they first emerged during the Middle Triassic (247 million to 237 million years ago).

In Australia were allowed to kill kangaroos

Under the new system, carcasses will no longer need to be tagged and left in the paddock and landholders will be able to use the carcass for a range of noncommercial purposes such as bait meat. The government should have subsidised professional hunters to reduce kangaroo numbers more humanely, he said.
