| 1 | The first pterosaur 3-D egg:Implications for Pterodaustro guinazui nesting strategies,an Albian filter feeder pterosaur from central Argentina显示文摘The increasing number of fossil pterosaur eggs sheds light on nesting environments and breeding behaviors of these extinct flying reptiles.Here we report the first partial three-dimensional egg of the pterosaur,Pterodaustro guinazui,from central Argentina.The specimen was discovered from the same Albian deposits as the exceptional P.guinazui embryo described in 2004.Microscopic characterizations indicate a pristine preservation of the 50 mm thick calcium carbonate,which differs significantly from the soft shell of Chinese pterosaur eggs.Estimate of the eggshell conductance implies that the nest had a minimum moisture content of 75%.This moisture estimate,combined with geological and taphonomical data,suggests that P.guinazui may have adopted a nesting strategy similar to those of grebes and flamingos rather than being buried on land,as previously hypothesized.Moreover,our results demonstrate that the nesting paleoenvironment of this pterosaur species was closely linked to a mesohaline lacustrine ecosystem in a basin governed by regional tectonic subsidence,a setting characteristic for the feeding and reproduction of modern flamingos. | Gerald Grellet-Tinner Michael B.Thompson Lucas E.Fiorelli Eloísa Argaaraz Laura Codorniú E.Martín Hechenleitner | 2014 | Geoscience Frontiers2014，5，6： | 2 |
| 2 | Generalized Derivations Acting on Multilinear Polynomials in Prime Rings and Banach Algebras显示文摘Let R be a prime ring of characteristic different from 2 with Utumi quotientring U and extended centroid C,F and G,the two nonzero generalized derivationsof R,I an ideal of R and f(x1,...,xn)a multilinear polynomial over C which is notcentral valued on R.If F(G(f(x1,...,Xn))f(X1,...,Xn))=0 for all x1,...,Xn∈1,then one of the followings holds:(1)there exist a,b c Usuch that F(x)=ax and G(x)=bx for all x c R with ab=0;(2)there exista,b,p c U such that F(x)=ax+xb and G(x)=px for all x c R with F(p)=0and f(x1,...,xn)’is central valued on R.We also obtain some related results in caseswhere R is a semiprime ring and Banach algebra. | Basudeb Dhara Nurcan Argaç | 2016 | Communications in Mathematics and Statistics2016，4，1： | 2 |
