Hartman Prehistoric Garden
The Hartman Prehistoric Garden is a botanical garden within the Zilker Botanical Garden in Austin, Texas, USA. In January 1992 Karen and Dr. Mike Duffin discovered dinosaur footprints in Zilker Park in a quarry which had recently been cleared for the installation of a butterfly garden. Dr. Duffin contacted Professor Wann Langston, Director Emeritus of the Vertebrate Paleontology Laboratory of the Texas Memorial Museum. The fossils of more than 100 preserved tracks made by six or seven prehistoric reptiles, along with the bones of an ancient turtle were discovered. Immediately they began to study the best means of preserving the tracks. They were mapped and casts were made, and then they were reburied to prevent further deterioration due to exposure to the elements. A major funding drive was undertaken and many volunteers helped to develop the site and around it as a Cretaceous habitat. The plants chosen to populate the garden were those believed to have existed at the time the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marchantiophyta
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

History Of Austin, Texas
The recorded history of Austin, Texas, began in the 1830s when Anglo-American settlers arrived in Central Texas. In 1837 settlers founded the village of Waterloo on the banks of the Colorado River (Texas), Colorado River, the first permanent settlement in the area. By 1839, Waterloo would adopt the name Austin, Texas, Austin and become the capital of the Republic of Texas. Austin's history has also been largely tied to state politics and in the late 19th century, the establishment of the University of Texas at Austin, University of Texas made Austin a regional center for higher education, as well as a hub for state government. In the 20th century, Austin's Music of Austin, music scene had earned the city the nickname "Live Music Capital of the World." With a population of over 800,000 inhabitants in 2010, Austin is experiencing a population boom. During the 2000s (decade) Austin was the third fastest-growing large city in the nation.

The Countryman Press
W. W. Norton & Company is an American publishing company based in New York City. Established in 1923, it has been owned wholly by its employees since the early 1960s. The company is known for its Norton Anthologies (particularly ''The Norton Anthology of English Literature'') and its texts in the Norton Critical Editions series, both of which are frequently assigned in university literature courses. History and overview The roots of the company date to 1923, when William Warder Norton founded the firm with his wife Mary Dows Herter Norton, and became its first president. In the 1960s, Mary Norton offered most of her stock to its leading editors and managers. Storer D. Lunt took over in 1945 after Norton's death, and was succeeded by George Brockway (1957–1976), Donald S. Lamm (1976–1994), W. Drake McFeely (1994–2017), and Julia A. Reidhead (2017–present). Reidhead was vice president and publishing director of Norton's College division and a former editor of the Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithomimus
''Ornithomimus'' (; "bird mimic") is a genus of ornithomimid dinosaurs from the Late Cretaceous Period of what is now North America. ''Ornithomimus'' was a swift bipedal theropod which fossil evidence indicates was covered in feathers, equipped with a small toothless beak that may indicate an omnivorous diet. It is usually classified into two species: the type species, ''Ornithomimus velox'', and a referred species, ''Ornithomimus edmontonicus''. ''O. velox'' was named in 1890 by Othniel Charles Marsh on the basis of a foot and partial hand from the late Maastrichtian-age Denver Formation of Colorado, United States. Another seventeen species have been named since, though most of them have subsequently been assigned to new genera or shown to be not directly related to ''Ornithomimus velox''. The best material of species still considered part of the genus has been found in Alberta, Canada, representing the species ''O. edmontonicus'', known from several skeletons from the early Maast ...

Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Magnolia
''Magnolia'' is a large genus of about 210 to 340The number of species in the genus ''Magnolia'' depends on the taxonomic view that one takes up. Recent molecular and morphological research shows that former genera ''Talauma'', ''Dugandiodendron'', ''Manglietia'', ''Michelia'', ''Elmerrillia'', ''Kmeria'', ''Parakmeria'', ''Pachylarnax'' (and a small number of monospecific genera) all belong within the same genus, ''Magnolia'' s.l. (s.l. = ''sensu lato'': 'in a broad sense', as opposed to s.s. = ''sensu stricto'': 'in a narrow sense'). The genus ''Magnolia'' s.s. contains about 120 species. See the section Nomenclature and classification in this article. flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. ''Magnolia'' is an ancient genus. Appearing before bees evolved, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpe ...

Ginkgo
''Ginkgo'' is a genus of non-flowering seed plants. The scientific name is also used as the English name. The order to which it belongs, Ginkgoales, first appeared in the Permian, 270 million years ago, and is now the only living genus within the order. The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene. The sole surviving species, ''Ginkgo biloba'' is only found in the wild in China, but is cultivated around the world. The relationships between ginkgos and other groups of plants are not fully resolved. Prehistory The ginkgo (''Ginkgo biloba'') is a living fossil, with fossils similar to the modern plant dating back to the Permian, 270 million years ago. The closest living relatives of the clade are the cycads, which share with the extant ''G. biloba'' the characteristic of motile sperm. The ginkgo and cycad lineages are thought to have an extremely ancient divergence dating to the early Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk (botany), trunk with a crown (botany), crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for Arecaceae, palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their fertilization, unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobilus, strobili), somewhat similar to conife ...

Horsetail
''Equisetum'' (; horsetail, snake grass, puzzlegrass) is the only living genus in Equisetaceae, a family of ferns, which reproduce by spores rather than seeds. ''Equisetum'' is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests. Some equisetids were large trees reaching to tall. The genus ''Calamites'' of the family Calamitaceae, for example, is abundant in coal deposits from the Carboniferous period. The pattern of spacing of nodes in horsetails, wherein those toward the apex of the shoot are increasingly close together, is said to have inspired John Napier to invent logarithms. Modern horsetails first appeared during the Jurassic period. A superficially similar but entirely unrelated flowering plant genus, mare's tail (''Hippuris''), is occasionally referred to as "horsetail", and adding to confusion, the name "mare's tail" is sometimes ap ...
