The official journal of the International Palaeontological Association (IPA), Lethaia publishes articles of international interest in the fields of palaeontology and stratigraphy. The articles concentrate on the development of new ideas and methods and descriptions of new features of wide significance rather than routine descriptions. Palaeobiology and ecostratigraphy are the core topics of the journal. In addition to articles, Lethaia contains shorter contributions in the form of discussions, presentations of current scientific activities, reviews and editorials. Lethaia was launched in 1968 as a joint venture between scientists in Denmark, Norway, and Sweden, with the aim of promoting the development of modern methods in scientific publishing and of providing a medium for rapid publication of well-prepared manuscripts of wide international interest., totalCites=2338, brief=LETHAIA杂志地学行业，“<strong><a target="_blank" href="/sci/index.do?smallclass=古生物学" >古生物学</a></strong>”子行业的中等级别杂志, articleType=论著，综述各类型文章都接收, medsciHeat=黑红, medsciComment=LETHAIA在该细分领域可能是一流杂志，可能是创刊时间短或不是热门学科，整体来说，国内学者关注度仍然不够。对于投稿而言，建议多向"&abbr&"投稿，当然期刊也应该加强品牌宣传。, medsciExplanation=MedSci期刊指数是根据中国科研工作者（含医学临床，基础，生物，化学等学科）对SCI杂志的认知度，熟悉程度，以及投稿的量等众多指标综合评定而成。当然，具体的，您还可以结合“<a href='https://www.medsci.cn/sci/submit.do?id=ac844581'>投稿经验系统</a>”，进行综合判断，这更是大家的实战经验，值得分享和参考。<br> 注意，上述MedSci期刊指数采用MedSci专利技术，由计算机系统自动计算，并给出建议，存在不准确的可能，仅供您投稿选择杂志时参考。, tags=null, citeScoreList=[GetImpactFactorCiteScoreListResponse(year=2017, citescore=1.8), GetImpactFactorCiteScoreListResponse(year=2018, citescore=1.79), GetImpactFactorCiteScoreListResponse(year=2019, citescore=4.1), GetImpactFactorCiteScoreListResponse(year=2020, citescore=4.1), GetImpactFactorCiteScoreListResponse(year=2023, citescore=3.3)], medsciIndexList=[GetImpactFactorMedsciIndexListResponse(year=2020, medsciHotlight=1.492), GetImpactFactorMedsciIndexListResponse(year=2021, medsciHotlight=0.965), GetImpactFactorMedsciIndexListResponse(year=2022, medsciHotlight=0.891), GetImpactFactorMedsciIndexListResponse(year=2023, medsciHotlight=0.859), GetImpactFactorMedsciIndexListResponse(year=2024, medsciHotlight=1.106)], citeScoreGradeList=[GetImpactFactorCiteScoreGradeResponse(smallClass=Earth and Planetary Sciences - Paleontology , rank=21/95), GetImpactFactorCiteScoreGradeResponse(smallClass=Agricultural and Biological Sciences - Ecology, Evolution, Behavior and Systematics , rank=198/591)], totalJcrAreaList=[GetImpactFactorCiteScoreGradeResponse(smallClass=PALEONTOLOGY, rank=Q1)], pmcUrl=https://www.ncbi.nlm.nih.gov/nlmcatalog?term=0024-1164[ISSN], pubmedUrl=https://www.ncbi.nlm.nih.gov/pubmed?cmd=search&term=LETHAIA[ta], article_number=27, article_number_cn=2, earlyWarning=null, linkOutUrl=null, isJournalMember=false, unscrambleContent=null, dayViewCount=false, endexampletyle=暂无数据)
