एडेनंथोस क्यूनेटस (खेती की जाती है, जिसे एडेनंथोस क्यूनेटा एफ। प्रोस्ट्रेट के रूप में लेबल किया जाता है)। Adenanthos cuneatus, also known as coastal jugflower, flame bush, bridle bush and sweat bush, is a shrub of the family Proteaceae native to the south coast of Western Australia. The French naturalist Jacques Labillardière originally described it in 1805. Within the genus Adenanthos, it lies in the section Adenanthos and is most closely related to A. stictus. A. cuneatus has hybridized with four other species of Adenanthos. Growing to 2 m (6 ft 7 in) high and wide, it is erect to prostrate in habit, with wedge-shaped lobed leaves covered in fine silvery hair. The single red flowers are insignificant, and appear all year, though especially in late spring. The reddish new growth occurs over the summer.

एटेलोपस सर्टिफिकेट कॉलिंग मेल edit.jpg Atelopus certus, the Darien stubfoot toad or Toad Mountain harlequin frog, is a species of toad in the family Bufonidae endemic to Panama.

Anning searched for fossils in the area's Blue Lias cliffs, particularly during the winter months when landslides exposed new fossils that had to be collected quickly, before they were lost to the sea. It was dangerous work, and she nearly lost her life in 1833 during a landslide that killed her dog Tray. Her discoveries included the first ichthyosaur skeleton to be correctly identified, which she and her brother Joseph found when she was just twelve years old; and the first two plesiosaur skeletons ever found. Her observations played a key role in the discoveries that belemnite fossils contained fossilised ink sacs, and that coprolites, known as bezoar stones at the time, were fossilised faeces.

Anning's gender and social class prevented her from fully participating in the scientific community of 19th-century Britain—dominated as it was by wealthy Anglican gentlemen. She struggled financially for much of her life. Her family were poor, and as religious dissenters were subject to legal discrimination. Her father, a cabinetmaker, died when she was eleven. She became well known in geological circles around the world, and was consulted on issues of anatomy as well as about collecting fossils. However, as a woman she was not eligible to join the Geological Society of London, and she did not always receive full credit for her scientific contributions. Indeed she wrote in a letter: "The world has used me so unkindly, I fear it has made me suspicious of everyone." The only scientific writing of hers published in her lifetime appeared in the Magazine of Natural History in 1839, an extract from a letter which Anning had written to the magazine's editor questioning one of its claims. After her death her unusual life story attracted increasing interest. Charles Dickens wrote of her in 1865 that "[t]he carpenter's daughter has won a name for herself, and has deserved to win it."
