多齒何信祿龍
Hexinlusaurus multidens
(He & Cai, 1983)
|
何信祿龍（学名：Hexinlusaurus）是種原始鸟臀目恐龍，是一种小型的二足草食性恐龍，生活在侏罗纪中期，化石發現於中国四川省自贡市大山铺，由成都理工大學的何信禄和蔡开基在1983年敘述及命名。
何信祿龍的正模標本（編號ZDM T6001）包含一個幾乎完整的頭顱骨，以及部份頭顱後骨骸，發現於大山铺的下沙溪廟組陸相沙岩層，年代相當於侏羅紀的巴柔階。副模標本（編號ZDM T6002）是一個部份頭顱骨與顱後的骨骼。
多齒何信祿龍原本為多齒鹽都龍（Yandusaurus multidens），保羅·巴雷特（Paul Barrett）等人在2005年將牠們成立獨立的屬，並認為牠們與其他基礎鳥腳類恐龍的差別在於單一獨有衍徵（Autapomorphy）：眶後的側面有一個明顯的凹面。屬名是以最初的命名者何信祿為名。
其他生存於大山铺地區的恐龍包括：蜥腳下目的蜀龍、獸腳亞目的氣龍、以及劍龍下目的華陽龍。
原鹽都龍
這個物種被正式命名為何信祿龍之前，這種恐龍被非正式名稱為原鹽都龍（"Proyandusaurus"）。這個名稱最初出現在Fabien Knoll的研究概論之中[1][2]。

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
