Abstract

© 2018, © by the Society of Vertebrate Paleontology. The holotype of Concavenator corcovatus (MCCM-LH 6666) is a carcharodontosaurid skeleton from the Lower Cretaceous Las Hoyas fossil site in Spain. The appendicular skeleton of Concavenator is the most complete for any Carcharodontosauridae, with only a few regions absent. We describe the limb osteology of Concavenator and carry out an anatomical comparison with other theropods. The results show that Concavenator presents several allosauroid and carcharodontosaurid synapomorphies. Concavenator shares with other allosauroids symmetric glenoid rims of the scapulacoracoid, a canted orientation of the proximal and distal humeral ends, an anterior position of the humeral condyle on the distal end, a long manus relative to the forearm, curved ungual phalanges, a posteriorly broad brevis fossa in the ilium, a reduced ischial tuberosity, a posterior flange on the iliac peduncle of the ischium, and a reduced distal tubercle in the ischium. A concavity on the middle of the proximomedial surface of the humeral head is postulated as a new synapomorphy of carcharodontosaurids. We propose some autapomorphies of Concavenator regarding the length of the phalanges of digit III, the height of the olecranon process relative to ulna length, the proportions of the deltopectoral crest, and the projection of the preacetabular hook in the ilium. The osteological description of the complete appendicular skeleton of Concavenator provides some novelties in the limbs of carcharodontosaurids and is relevant to understanding its general phylogenetic relationships.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal JOURNAL OF VERTEBRATE PALEONTOLOGY due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2018, it was in position 12/56, thus managing to position itself as a Q1 (Primer Cuartil), in the category Paleontology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.33. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.74 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 3.75 (source consulted: Dimensions Jun 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-06-19, the following number of citations:

  • WoS: 13
  • Scopus: 20
  • Google Scholar: 16
  • OpenCitations: 16

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-19:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 31.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 31 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 64.78.
  • The number of mentions on the social network Facebook: 1 (Altmetric).
  • The number of mentions on the social network X (formerly Twitter): 67 (Altmetric).
  • The number of mentions on Wikipedia: 5 (Altmetric).
  • The number of mentions in news outlets: 2 (Altmetric).
