Parafaveoloolithus
open-in-new
<h2 id="description">Description</h2> <p><i>Parafaveoloolithus</i> is diagnosed by its spherical or oval eggs, with a single layer of eggshell units (or a two superimposed layers in some portions). The growth lines of the shell units are undefined. Shell units are prismatic, and separated near the surface of the eggshell.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> <h2 id="oospecies">Oospecies</h2> <p><i>Parafaveoloolithus</i> contains six oospecies: </p> <ul><li><i>P. microporus</i> - Spherical eggs from the <a href="/facts/Tiantai_County/keBvDtQv">Tiantai basin</a> with a single layer of eggshell units. They are roughly 14 cm in diameter, with an eggshell that is 2.2-2.35 mm thick. It is very similar to <i><a href="/facts/Faveoloolithus/vTWlSazo">Faveoloolithus ningxiaensis</a></i>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a></li> <li><i>P. xipingensis</i> - Described in <a href="/facts/1998_in_paleontology/XhXQtGoT">1998</a> as a species of <i><a href="/facts/Youngoolithus/PUpHftlJ">Youngoolithus</a></i>. It is from the <a href="/facts/Upper_Cretaceous/pcHa4fBg">Upper Cretaceous</a> of <a href="/facts/Xixia_County/Hux2kyLx">Xixia County</a>, <a href="/facts/Henan_Province/jCKtYLXv">Henan Province</a>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> It was moved to <i>Parafaveoloolithus</i> because of its slender prismatic shell units and straight pores.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a></li> <li><i>P. macroporus</i> - Oval eggs, known from the Tiantai basin, with large pore canals. The eggs are symmetrical, and about 13 cm in diameter.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a></li> <li><i>P. tiansicunensis</i> - Also from Tiantai, <i>P. tiansicunensis</i> is very similar to <i>P. microporus</i> and <i>P. macroporus</i>, but it has a thinner shell and the pore canals narrow sharply near the outer surface of its shell.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a></li> <li><i>P. guoqingsiensis</i> - Spherical eggs 18.7 cm in diameter, native to Tiantai, with numerous pores looking like a honeycomb in cross-section. This oospecies was originally described as an oospecies of <i><a href="/facts/Dendroolithus/0yKpESgd">Dendroolithus</a></i> by Fang <i>et al.</i> (2000), but was moved to <i>Parafaveoloolithus</i> by Wang <i>et al.</i> (2011).<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a></li> <li><i>P. pingxiangensis</i> - This oospecies, first described by Zou <i>et al.</i> (2013), is quite distinct from the other <i>Parafaveoloolithus</i> oospecies because its shell is composed of several superimposed shell units. It was classified in <i>Parafaveoloolithus</i> because of the shell units assembling in the upper and middle portions of the shell. It is native to the Pingxiang basin of <a href="/facts/Jiangxi_Province/mFb3o7r4">Jiangxi Province</a>.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Zhang, S.K. 2010.
