真假鲸龙是怎么回事
19世纪上半叶，理查德?欧文发现了一种恐龙，他认为它是海中的巨大鳄鱼。后来，有学者比较了鲸龙的化石，认为是鲸龙，因为它确实与鲸龙非常相似。这种恐龙生活于侏罗纪中期至晚期的英格兰，距今约170万年前。它的体长约有15米，是四足行走的草食性恐龙，颈长头小，较其他蜥脚下目原始及尾巴较短。
1840年末及1868年，更多的肢骨和另一个接近完整的骨骼分别被发现。随着研究的深入，专家否认了这种恐龙是鲸龙的看法。1972年，一位名叫许纳的美国古生物学家将其命名为似鲸龙，即“像鲸龙的恐龙”。

恐龙有哪些种类越详细越好
恐龙的种类很多，科学家们根据它们骨胳化石的形状，把它们分成两大类，一类叫做鸟龙类，一类叫做蜥龙类。根据它们的牙齿化石，还可以推断出是食肉类还是食草类。这只是大概的分类，根据恐龙骨胳化石的复原情况，我们发现，其实恐龙不仅种类很多，它们的形状更是无奇不有。这些恐龙有在天上飞的，有在水里游的，有在陆上爬的。1、翼手龙生活在白垩纪，它们的骨胳在欧洲被发现。翼手龙并不是很大，它的翅膀不过22厘米左右。但是风神翼龙的翅膀却长达12米，像公共汽车那么大。美国科学家曾经发现过一种翼龙，它的翅膀长达15米以上，如果我们今天能看到它，说不定会以为是飞机在天上飞呢。很多会飞的鸟龙都有些像今天的蝙蝠，它们好像用一双手撑起巨大的翅膀，于是，又有翅膀又有利爪成了它们的一大特点。有人认为，后来的鸟类就是由它们演化来的。2、雷龙是恐龙中最大的一种，有的身长达30米以上，有6层楼那么高。它们都是食草或树叶的动物。我们在博物馆见到的一些恐龙化石，大多就是这种恐龙。3、霸王龙就是非常凶猛的肉食恐龙。它大脑袋，短身子，牙齿就像锋利无比的匕首。4、薄板龙是最长的蛇颈龙，全长可达15米。它的脖子大约为躯干的两倍。它们与陆地上的恐龙和空中的翼龙是近亲，也用肺呼吸空气，一般也产卵。它们是海洋中的霸主，有些长着锋利的牙齿，为的是捕食其他鱼类。中国的恐龙种属名录[正式版]蒋澈邢立达恐龙纲ClassDinosauria（Owen）,1841◆蜥臀目[OrderSaurischiaSeeley,1888]◆兽脚亚目SuborderTheropodaMarsh,1881◆虚骨龙次亚目InfraorderCoelurosauriaHuene,1914迅足龙科FamilyPodokesauridaeHuene,1914芦沟龙属LukousaurusYoung,1948⊙尹氏芦沟龙LukousaurusyiniYoung,1948虚骨龙科FamilyCoeluridaeMarsh,1881中国虚骨龙属SinocoelurusYoung,1922⊙破碎中国虚骨龙SinocoelurusfragilisYoung,1942川东虚骨龙属ChuandongocoelurusHe,1984⊙原始川东虚骨龙ChuandongocoelurusprimitivusHe,1984似鸟龙科FamilyOrnithomimidaeMarsh,1890古似鸟龙属ArchaeornithomimusRussell,1972⊙亚洲古似鸟龙Archaeornithomimusasiatiicus（Gilmore,1933）Russell,1972偷蛋龙科FamilyOviraptoridaeBarshold,1976偷蛋龙属OviraptorOsborn,1924⊙嗜角偷蛋龙OviraptorphiloceratopOsborn,1924驰龙科FamilyDromaeosauridaeMattewetBrown,1922敏捷龙属PhaedrolosaurusDong,1973⊙艾里克敏捷龙PhaedrolosaurusilikensisDong,1973吐谷鲁龙属TugulusaurusDong,1973⊙小巧吐谷鲁龙TugulusaurusfacilesDong,1973疾走龙属VelociraptorOsborn,1924⊙蒙古疾走龙VelociraptormongoliensisOsborn,1924◆肉食龙次亚目InfraorderCarnosauriavonHuene,1920巨齿龙科FamilyMegalosauridaeHuxley,1870中国龙属SinosaurusYoung,1948⊙三叠中国龙SinosaurustriassicusYoung,1948只脊龙属DilophosaurusWelles,1970⊙中国只脊龙DilophosaurussinensisHu,1992气龙属GasosaurusDongetTang,1985⊙建设气龙GasosaurusconstructusDongetTang,1985宣汉龙属XuanhanosaurusDong,1984⊙七里峡宣汉龙XuanhanosaurusqilixiaensisDong,1984异特龙科FamilyAllosauridaeMarsh,1879永川龙属YangchuanosaurusDonget.al.1978⊙上游永川龙YangchuanosaurusshangyouensisDonget.al.,1978⊙巨型永川龙YangchuanosaurusmagusDonget.al.,1983四川龙属SzechuanosaurusYoung,1942⊙甘氏四川龙SzechuanosauruscampiYoung,1942克拉玛依龙属KelmayisaurusDong,1973⊙石油克拉玛依龙KelmayisauruspetrolicusDong,1973吉兰泰龙属ChilantaisaurusHu,1964⊙大水沟吉兰泰龙ChilantaisaurustashikouensisHu,1964⊙毛儿图吉兰泰龙ChiantaisaurusmaortuensisHu,1964⊙浙江吉兰泰龙ChilantaisauruszhejiangensisDong,1979金刚口龙属ChingkankousaurusYoung,1958⊙破碎金刚口龙ChingkankousaurusfragilisYoung,1958恐齿龙属ProdeinodonOsborn,1924⊙广西原恐齿龙ProdeinodonKwangshiensisHouet.al.,1975鄯善龙科FamilyShanshanosauridaeDong,1977鄯善龙属ShanshanosaurusDong,1977⊙火焰山鄯善龙ShanshanosaurushuoyanshanensisDong,1977暴龙科FamilyTyrannosauridaeOsborn,1905阿尔伯脱龙属AlbertosaurusOsborn,1905⊙威肋阿尔伯脱龙AlbertosauruspericulosusRiabinin,1930鹰龙属AlectrosaurusGilmore,1933⊙奥氏鹰龙AlectrosaurusolseniGilmore,1933暴龙属TyrannosaurusOsborn,1905⊙栾川暴龙TyrannosaurusluanchuanensisDong,1979⊙霸王龙相似种Tyrannosauruscf.T.rexHu,1973⊙特暴龙未定种Tarbosaurussp.Maleev,1955◆蜥脚形亚目SuborderSauropodomorphavonHuene,1932◆原蜥脚次亚目InfraorderProsauropodavonHuene,1920板龙科FamilyPlatesauridaeMarsh,1895禄丰龙属LufengosaurusYoung,1941⊙许氏禄丰龙LufengosaurushueneiYoung,1941⊙巨型禄丰龙LufengosaurusmagnusYoung,1947云南龙科FamilyYunnanosauridaeYoung,1942云南龙属YunnanosaurusYoung,1942⊙黄氏云南龙YunnanosaurushuangiYoung,1942⊙巨硕云南龙YunnanosaurusmagnusYoung,1947近蜥龙科FamilyAnchisauridaeMarsh,1885讯蜥龙属AnchisaurusMarsh,1885兀龙亚属GyposaurusBroom,1911⊙中国近蜥龙（兀龙）Anchisaurus（Gyposaurus）sinensisYoung,1941美兰龙科FamilyMelanrosauridaevonHuene,1929金沙江龙属ChinshakiangosaurusYeh,1975⊙中和金沙江龙ChinshakiangosauruszhongheensisElaao,1956◆蜥脚次亚目InfraorderSauropodaMarsh,1878圆顶龙科FamilyCamarasauridaeCope,1877蜀龙亚科SubfamilyShunosaurinaeMclntosh,1990昆明龙属KunmingosaurusZhao,1985⊙武定昆明龙KunmingosauruswudingensisZhao,1985原颌龙属ProtognathosaurusOlshevsky,1991⊙炎齿原颌龙Protognathosaurusoxyodon（Zhang,1988）Olshevsky,1991三巴龙属SanpasaurusYoung,1944⊙岳氏三巴龙SanpasaurusyoaiYoung,1944资中龙属ZizhongosaurusDongetal.,1983⊙船城资中龙ZizhongosauruschuanchengensisDongetal.,1983蜀龙属ShunosaurusDong.ZhouetZhang,1983⊙李氏蜀龙ShunosaurusliiDong,et.al.,1983似鲸龙亚科SubfamilyCetiosaurinaeLydekker,1888酋龙属Datousaurus⊙巴以酋龙DatousaurusbashanensisDongetTang,1984巧龙亚科SubfamilyBellusaurinaeDong,1986马门溪龙科FamilyMamenchisauridaeYoungetChao,1972马门溪龙亚科SubfamilyMamenchisaurinaeDong,1992峨嵋龙属GenusOmeisaurusYoung,1939⊙荣县峨嵋龙OmeisaurusjunghsiensisYoung,1939⊙斧溪峨嵋龙OmeisaurusfuxiensisDonget.al.,1983⊙天府峨嵋龙OmeisaurustianfuensisHeet.al.,1984⊙罗泉峨嵋龙OmeisaurusluoquanensisLi,1988马门溪龙属GenusMamenchisaurusYoung,1954⊙建设马门溪龙MamenchisaurusconstructusYoung,1954⊙合川马门溪龙ManenchisaurushochuanensisYoungetZhao,1972盘足龙亚科SubfamilyEuhelopodinaeRomer,1956天山龙属TienshanosaurusYoung,1937⊙奇台天山龙TienshanosauruschitaiensisYoung,1937美丽龙属KlamelisaurusZhao,1993⊙戈壁克拉美丽龙KlamelisaurusgobiensisZhao,1993嘉裕龙属ChiayusaurusBohlin,1953⊙湖泊嘉裕龙ChiayusauruslacstrisBohlin,1953盘足龙属EuhelopusRomer,1956⊙师氏盘足龙EuhelopuszdanskyiWiman,1929亚洲龙属AsiatosaurusOsborn,1924⊙广西亚洲龙AsiatosauruskwangshiensisHouet.al.,1975蒙古龙属MongolosaurusGilmore,1933⊙坦齿蒙古龙MongolosaurushoplodonGilmore,1933梁龙科FamilyDiplodocidaeMarsh,1884巨龙亚科SubfamilyTitanosaurinaeNopcsa,1928纳摩盖吐龙属NemegtosaurusNowinski,1971⊙耙齿纳摩盖吐龙NemegtosauruspachiDong,1977◆鸟臀目[OrderOrnithischiaSeeley,1887]◆鸟脚亚目SuborderornithopodaMarsh
