Gerard Smets
Gerard Smets (-after 1895) was a Belgian paleontologist, scientist, and abbé known for the misidentification of the plant genus ''Aachenosaurus'', named after the locale of Aachen. Biography He was born around 1857, possibly in Gotem, Belgium, and he died after 1895. History of the ''Aachenosaurus'' ''Aachenosaurus'' was found by Smets in 1887; he named the species '' Aachenosaurus multidens'' on October 31, 1888. Based on these fragments he determined that the specimen was a hadrosaur reaching an estimated 4-5 meters in length which might have had dermal spines. He defended this conclusion, citing that the fossils had been examined visually with the naked eye, magnifying lenses and with the microscope. However, his error was soon demonstrated by Louis Dollo. Smets at first tried to defend his original identification but was again proven wrong by a neutral commission. A rumor abounded that he completely withdrew from science out of pure embarrassment, but not until he had publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat ...

Louis Dollo
Louis Antoine Marie Joseph Dollo ( Lille, 7 December 1857 – Brussels, 19 April 1931) was a Belgian palaeontologist, known for his work on dinosaurs. He also posited that evolution is not reversible, known as Dollo's law. Together with the Austrian Othenio Abel, Dollo established the principles of paleobiology. Early life Louis Dollo was born in Lille, Nord-Pas-de-Calais, a scion of an old Breton family. He studied at the École centrale de Lille, with geologist Jules Gosselet and zoologist Alfred Giard, both of whom influenced the young Dollo. In 1877, he graduated with a degree in engineering. After his graduation, he worked in the mining industry for five years, but simultaneously developed a passion for paleontology. In 1879, he moved to Brussels. ''Iguanodon'' spp. For three years, starting in 1878, he supervised the excavation of the famous, multiple '' Iguanodon'' find at Bernissart, Belgium. He devoted himself to their study as a scientific passion, initially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hadrosaur
Hadrosaurids (), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as ''Edmontosaurus'' and ''Parasaurolophus'', was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, South America and Antarctica. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effecti ...

Aachenosaurus Multidens
''Nicolia'' is a genus of fossilized wood from the Late Cretaceous (Santonian- Campanian). At one time, specimens were misidentified as a jaw fragments of a hadrosaur and named ''Aachenosaurus''.H. N. Andrews. (1970). Index of Generic Names of Fossil Plants, 1820-1965. ''Geological Survey Bulletin'' 1-354 Taxonomy The genus and sole species ''Nicolia aegyptiaca'' were named in 1842 by Unger. Independently in 1887, the name ''Aachenosaurus'' was created by the scientist (and abbé) Gerard Smets based on fossilized fragments of material that he thought were jaw fragments from a duck-billed dinosaur (a hadrosaur). However, the fossils turned out to be petrified wood, to the great embarrassment of the discoverer. The name ''Aachenosaurus'' means "Aachen lizard", named for the Aachen Formation The Aachen Formation ( nl, Formatie van Aken, german: Aachen-Formation) is an Upper Cretaceous geologic formation in the southern Netherlands and northeastern Belgium and adjacent German ...

Abbé
''Abbé'' (from Latin ''abbas'', in turn from Greek , ''abbas'', from Aramaic ''abba'', a title of honour, literally meaning "the father, my father", emphatic state of ''abh'', "father") is the French word for an abbot. It is the title for lower-ranking Catholic clergy in France. History A concordat between Pope Leo X and King Francis I of France (1516) cites III under Kinds of Abbot gave the kings of France the right to nominate 255 commendatory abbots () for almost all French abbeys, who received income from a monastery without needing to render service, creating, in essence, a sinecure. From the mid-16th century, the title of ''abbé'' has been used in France for all young clergy, with or without consecration. Their clothes consisted of black or dark violet robes with a small collar, and they were tonsured. Since such ''abbés'' only rarely commanded an abbey, they often worked in upper-class families as tutors, spiritual directors, etc.; some (such as Gabriel Bonnot d ...

Scientist
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''
